Every vlogger has opened a clip and found their face the colour of a traffic cone, or a corpse. The camera was not broken. The white balance was set for a different light than the one in the room. This guide covers Kelvin in real rooms, presets versus a grey card, why auto mode drifts mid-take, and what to do when a window and a lamp disagree about your skin.
The short version
- Light has a colour, measured in Kelvin. Warm bulbs sit near 3,200 K, midday daylight near 5,600 K, shade higher still.
- White balance tells the camera which colour the light is, so whites, greys and skin record accurately under it.
- Auto white balance drifts on video. It re-judges the scene as you move, and the shift lands mid-take.
- Set it manually and lock it: a preset, a Kelvin number, or a grey card measurement, once per location.
- Mixed light cannot be balanced twice. Balance for the light on your face, then fix or accept the other.
- Judge the result on skin. Walls can be any colour. Faces tell the truth.

What white balance actually does
White balance is the camera correcting for the colour of the light. Every source tints a scene: bulbs push it orange, daylight pushes it blue. White balance tells the camera which tint to cancel, so a white shirt records as white and skin records as skin.
Your eyes do this automatically: walk into a bulb-lit room and the walls still look white, because your brain re-calibrates. A camera has no such instinct. It records the tint that is actually there, which is why footage under household bulbs looks filmed inside a pumpkin. The setting changes neither exposure nor the light itself, only how the camera interprets it, and fixing that one tint fixes the whole frame.
Kelvin, translated into rooms you film in
Colour temperature is measured in Kelvin (K). Low numbers are warm, orange light: a candle is about 1,800 K, a household bulb about 3,200 K. High numbers are cool, blue light: midday sun is about 5,600 K, open shade can pass 7,500 K. Set the camera to the Kelvin value of your light and it neutralises that light.
The direction confuses everyone at first, because a warm room has a low Kelvin number and a cold blue day has a high one. The scale is the colour metal glows as it heats, from dull orange to blue-white. For filming, these are the values that matter:
| Light you are filming in | Typical Kelvin | If the camera stays at 5,600 K |
|---|---|---|
| Candlelight, firelight | 1,800 to 2,000 K | Extreme orange. Rarely corrected; the glow is the point. |
| Warm household bulbs, tungsten lamps | 2,700 to 3,200 K | Strong orange cast, the classic indoor vlog problem. |
| Sunrise and sunset light | 3,000 to 3,800 K | Golden warmth. Usually kept, not corrected. |
| Fluorescent tubes, many cheap LEDs | 4,000 to 4,500 K | Slightly cool, often green. See tint, below. |
| Noon sun, daylight LED panels | 5,500 to 5,600 K | Neutral. The reference most cameras assume. |
| Overcast sky | 6,500 to 7,000 K | Mild blue cast on skin if uncorrected. |
| Open shade on a sunny day | 7,000 to 8,000 K | Clear blue cast. Shade is lit by sky, not sun. |
Match the number to the light hitting your face, not the background. The correction runs opposite to what you see: footage too orange means the light is warmer than the setting, so lower the number; too blue means raise it, in steps of 200 to 300 K.
Auto white balance drifts, and video shows every drift
Auto white balance (AWB) guesses the light colour from the frame, over and over, many times a second. Harmless on a still photo, it means the camera can change its mind mid-take on video, and the colour of your face visibly slides warmer or cooler while you talk.
Pan across a room and the frame fills with a blue sofa: the scene breathes colour as the camera re-judges. Walk from a window-lit hallway into a lamp-lit room and the correction lands in stages. Hold up a red product and your skin shifts in sympathy. Removing that drift later means keyframing corrections along with it. Auto also aims for neutral even when neutral is wrong: at golden hour it works hard to delete the warmth you went outside to film.
For two-second B-roll shots, small shifts between cuts are invisible, and AWB earns its keep there. For talking footage, where your face stays on screen, balance manually and lock it. White balance is one of several settings worth taking off auto; our guide to vlogging camera settings explained puts it alongside shutter speed, aperture and ISO.
Preset, Kelvin number or custom measurement
Every camera offers the same three manual routes. Presets (Daylight, Cloudy, Tungsten) are fast but approximate. A Kelvin number is fast, precise and repeatable across cameras. A custom measurement from a grey card is the most accurate, because the camera measures the actual light, tint included.
| Method | Speed | Accuracy | Best for |
|---|---|---|---|
| Preset | Fastest | Good when the light matches the label | Clear outdoor conditions, quick B-roll |
| Kelvin number | Fast | Good, identical on every camera | Two-camera shoots, rated LED panels |
| Custom (grey card) | About a minute | Best, it measures the real light | Fixed indoor setups, odd light |
Presets hide a wrinkle: the numbers behind the icons are not standardised. One brand’s Daylight sits at 5,200 K, another’s at 5,600 K. Fine on one camera, a genuine mismatch when two brands film the same scene. Kelvin also pairs with the lights themselves: most creator LED panels are rated at a stated temperature, or are bi-colour and can be dialled to one. Panel at 5,600 K, camera at 5,600 K, balanced before the first test shot. Our roundup of the best lights for vlogging covers the panels that make this easy. Custom measurement wins whenever the light is unusual, because instead of you estimating it, the camera samples it.
The grey card routine: custom white balance in under a minute
Hold a grey card where your face will be, angled toward the main light, filling most of the frame. Set your exposure, then run the camera’s custom white balance function to measure from that shot. The camera stores the correction, tint included, until you measure again.
- Put the card at the subject position. Not beside the camera, not on the desk. It must sit in the light that will fall on your face.
- Angle it halfway between the light and the lens, so it catches the key light the way skin does.
- Fill most of the frame, exposure set first. A badly exposed shot can fail to measure at all.
- Run the custom white balance function and store it. Brands bury it under names like Custom WB, PRE or Measure. Once stored, it stays fixed until you re-measure.
- Re-measure when the light changes: new room, lamp switched on, sun gone for good.
A manufactured grey card beats improvisation because it is neutral by design. Printer paper works in a pinch, but many papers carry brighteners that lean blue, and white overexposes easily mid-measurement. Painted walls are worse, because paint is rarely neutral. Film in one room most of the time and the card pays for itself in a week: measure once, store the slot, recall it every session.
Mixed light: the window says 5,600, the lamp says 3,200
One white balance setting corrects one colour of light. When window daylight and warm lamplight hit your face at once, no setting can neutralise both. Your options: remove one light, convert one light, or balance for the light on your face and let the other become part of the look.
Remove a light. The cheapest fix in all of video. Switch the warm ceiling light off and film by the window, or close the curtain and film by the lamp. One source means one colour, and one colour can always be balanced perfectly.
Convert a light. Swap the bulb near your setup for a daylight-balanced one, or dial a bi-colour panel to match the window at 5,600 K. Now both sources agree and one setting covers the room: the permanent fix for a regular filming corner. Our guide to lighting your face for videos goes deeper on placing that key light once its colour matches the room.
Commit to the key light. When neither light can change, balance for the one on your face and let the other read as atmosphere. Balanced for the window, skin looks right and the lamp glows a warm orange that reads as cosy depth. Balanced for the lamp, skin is right and the window goes cool blue. Splitting the difference never works: a halfway setting leaves the face half orange, half blue, wrong on both sides.
Positioning shrinks the problem before any setting does. Face the window and let the lamp fall behind you, or sit side-on so one source becomes your key and the other a rim. Mixed light is worst when both strike the face at similar strength from opposite sides, also the easiest arrangement to avoid by moving a chair.
Judge the result on skin, not on the wall
When you check a white balance, look at skin first. Viewers read faces instinctively and forgive almost any other colour error, but skin sits in a narrow band of hues everyone recognises. A white wall proves nothing, because paint, paper and shirts are often tinted on purpose.
Healthy skin, across every skin tone, shares one hue family: a warm orange-red that varies in depth and saturation but never runs green or magenta. Colourists use a dedicated vectorscope line for this; your eyes already know the target. Five-second checks: skin should not match a wooden door (too orange) or look grey and waxy (too blue), and the whites of the eyes should read clean without turning blue. Beware the classic trap: balancing until a cream wall looks pure white adds blue to the whole frame, and your skin pays the difference. Balance for the face. Let the wall be cream.
The second axis: green to magenta tint
Kelvin corrects only the blue-to-amber axis. Colour also shifts along a second axis, green to magenta, called tint. Fluorescent tubes and cheap LEDs push footage green along it, and no Kelvin number can fix that, because the error points in the other direction entirely.
This is the gap in most white balance advice: it treats colour as a one-slider problem. You slide Kelvin up and down, orange and blue come and go, and the sickly green stays exactly where it was: a tint error, from a green spike in the light’s spectrum.
Cameras give you two tools. A grey card custom balance measures both axes at once, the strongest argument for the card routine above. Most cameras also hide a white balance shift grid, green on one side, magenta on the other, for nudging the correction toward magenta to cancel a green cast. Move in small steps and check skin each time: push too far and you trade a green face for a pink one. Tint also explains two LED panels, both rated 5,600 K, that refuse to match. The Kelvin figure says nothing about a light’s green or magenta lean, and cheaper panels lean green. When two lights disagree, balance for the one on your face and push the other deeper into the background, where a slight cast reads as mood, not error.
Set it once per location, then leave it alone
The working habit: set white balance before the first take, lock it for the whole session in that spot, and revisit it only when the light itself changes. A new room, a lamp switched on, or the sun dropping all count as changes. Fidgeting mid-session does not.
- Dial in before the first shot. Grey card if the light is odd, Kelvin if you know it, preset if conditions are textbook. Then check skin.
- Balance with your ND filter fitted. Cheap variable NDs add a cast of their own, often green or magenta, and balancing without the filter bakes it in. Our explainer on ND filters for video covers why the cast happens.
- Use the same number on every camera. Two cameras on one conversation share a Kelvin value, or measure from the same grey card in the same light. Matching at the source is free.
- Lock it on a phone too. Phone cameras bury a white balance lock in pro mode, and filming apps expose it directly. A phone vlog drifts exactly like a camera vlog on auto.
- Protect golden hour from your own camera. Lock 5,600 K at sunset and the scene keeps the warmth you waited for. On auto, the camera spends the shoot deleting it.
Consistency beats perfection. A balance 200 K off but identical across every clip looks professional. A balance perfect per clip but different in each looks broken, because viewers see the jumps.
Shot it wrong anyway? What the edit can and cannot save
A single global cast in well-exposed footage corrects well in any editor: one temperature and tint adjustment usually fixes the whole clip. Three things resist rescue: mixed light, because one correction cannot fix two colours at once; a colour channel that clipped while recording; and basic 8-bit footage, which tears and bands when pushed hard.
The good news first. If the light was one colour and the setting simply wrong, the post fix is close to free, and log or 10-bit footage holds enough colour information to travel a long way without damage. That neutralise-and-match work is where our colour grading guide picks up.
Now the limits. When a colour channel clips, the information is gone: tungsten-lit footage on a daylight setting can blow out the red channel in skin highlights, and no slider rebuilds detail that was never recorded. Mixed light is the other wall, because correcting the orange side pushes the blue side further blue. The only fix is masking your face and correcting it separately, slow work across a whole vlog. Against that, the in-camera routine takes a minute with a card or ten seconds with a Kelvin number: the cheapest insurance in video, and one of the few mistakes software cannot fully buy back.
White balance questions, answered
Short answers to the questions vloggers ask about white balance, all following one thread: set it for the light on your face, then lock it.
What white balance should I use for indoor YouTube videos?
Match the light on your face, then lock it. Warm household bulbs call for roughly 3,200 K or a custom grey card measurement; a daylight LED panel calls for about 5,600 K. Custom is safest in a fixed setup, because it corrects green tint too.
Why does my face look orange in videos filmed indoors?
Your camera is set for daylight, around 5,600 K, while your room is lit by warm bulbs at around 3,200 K. The gap between the two is the orange. Lower the Kelvin setting to match the bulbs, or take a custom measurement.
Why does the colour keep shifting during my clips?
Auto white balance is re-judging the scene as your framing changes, and each new judgement shifts the colour. Switch to a preset, a Kelvin number or a stored custom balance and the shifting stops: the camera stops deciding mid-take.
What Kelvin value is daylight?
Midday sunlight is about 5,500 to 5,600 K, the figure daylight presets and LED panels use. The same sky reads 3,000 to 3,800 K near sunrise and sunset, and 7,000 K or more in open shade, so daylight is a range, not one number.
Is a grey card worth buying for vlogging?
For anyone filming in the same room regularly, yes. It makes custom balance a one-minute routine, measures tint as well as temperature, and gives you a stored setting to recall each session. If your locations change constantly, Kelvin numbers serve you better.
Can I fix white balance after recording?
A single overall cast, yes: temperature and tint sliders in any editor handle it, especially with log or 10-bit footage. Mixed light on a face, a clipped colour channel and casts baked into basic 8-bit footage are far harder, sometimes impossible, to fix cleanly.
What is the difference between temperature and tint?
Temperature moves colour between blue and amber, and is set in Kelvin. Tint moves it between green and magenta. Fluorescent lights and cheap LEDs add a green tint error on top of any temperature error, which is why footage can stay green after the Kelvin value looks right.
Should I use auto white balance outdoors?
For short B-roll clips it copes well. For anything longer, lock a manual value: walking between sun and shade makes auto hunt visibly. Set 5,600 K at midday, re-check as light drops.
How do I match white balance across two cameras?
Set the same Kelvin number on both, or measure a custom balance on each from the same grey card in the same light. Avoid presets: brands put different numbers behind the same names, so two cameras on “Daylight” can disagree by several hundred Kelvin.
Why do my LED lights make my skin look green?
Many inexpensive LEDs spike in the green part of their spectrum. That is a tint error, not a temperature error, so changing Kelvin will not remove it. Take a custom balance from a grey card, or nudge the camera’s white balance shift toward magenta.
