Key takeaways
- Neutral is #FFFFFF; Warm is #FFF0D6 and Extra Warm is #FFD5A3, which give roughly 88 % and 72 % of the light of Neutral.
- For the most light, choose Neutral, leave dimming at 0 % and turn the device brightness up. The dimming slider only lowers the colour values.
- The tone changes the preview and full screen, never the image you download.
Set up your light in three small steps.
- Choose Neutral, Warm or Extra Warm under Screen settings.
- Open full screen and adjust your device brightness to suit your space.
- Position the screen in front of you, out of the camera frame. A second display, separate window or another device can be useful during a call.
This screen light needs no camera access. The warm white shades are visual presets, not measured color temperatures. Results depend on your screen and room lighting.
Which tone should I choose for a video call?
Start with Neutral and look at your own camera preview. If your face looks cold or the room already has warm lamps, try Warm, then Extra Warm. The warmer presets lower the blue and green channels, which is why they also give less light.
| Preset | HEX | Light compared with Neutral | Good starting point when |
|---|---|---|---|
| Neutral | #FFFFFF | 100 % | The room is lit by daylight or cool ceiling lights |
| Warm | #FFF0D6 | about 88 % | White looks harsh or bluish on camera |
| Extra Warm | #FFD5A3 | about 72 % | Warm lamps are on and you want the screen to match |
Judge every preset through your camera rather than by its name; screens and rooms vary too much for a single best choice.
Where should the screen light go?
In front of you and roughly at face height, just outside what the camera sees. Light from a screen fades quickly as you move away, so a laptop or tablet a little closer to you helps more than a bigger screen further back. If you wear glasses and see a bright rectangle in the lenses, move the light slightly higher or off to one side.
A phone or tablet works as a second light on the other side. Open this page on it, switch to full screen and tap Keep screen awake so it does not go dark in the middle of the call.
Why does the light get darker when I use dimming?
Dimming multiplies the chosen tone by a factor, so 50 % on Neutral shows #808080, a mid grey. Your backlight stays at the same level. To soften the light without the grey cast, lower the device brightness instead and keep dimming at zero.
Light percentages are relative luminance as defined in WCAG 2, worked out from each preset's HEX code.
Questions, answered.
Does Screen Light use my camera or microphone?
No. It only shows a colour. Your call app keeps control of the camera, and this page never asks for permission to use it.
Can I use a white screen for Zoom lighting?
Yes, as an extra source of light. Keep your call visible in another window or on another screen. Full screen on the same display may cover the call interface.
Does warm light change the downloaded image?
No. Light tones change the preview and full screen only. The download panel shows the unchanged base color.
How do I leave full screen?
Press Escape or move your mouse or touch the screen to reveal Exit. Press F to toggle full screen when you are not typing in a field.
What does Keep screen awake do?
When supported and allowed, it asks your browser to keep the display on while this page is visible. The status shows whether the request is active, released or unavailable. Battery settings and system behavior may override it.
