MAKE IT YOURS
A comfortable glow.
Visual dimming only. Use device settings to change physical display brightness.
Warm and cool are approximate tints, not calibrated colour temperatures.
The preview and instructions work without JavaScript. Fullscreen, guided results and lighting adjustments require JavaScript; enable it to use those controls.
A SIMPLE LIGHT SOURCE
Set the tone. Find a comfortable position.
Use the white panel to add light near a video call or simple photo setup. Neutral is pure white at 100% visual intensity; warm and cool are approximate display tints, not calibrated colour temperatures.
- Place the display securely near your camera, outside the shot. Change its angle or distance to see how the light falls.
- Choose a tone and adjust screen light intensity. This changes the rendered colour, not your device’s physical brightness setting.
- Open fullscreen if you want a larger field. Tap to reveal the exit button when you are finished.
Adjust placement before turning up the light
Use these as setup suggestions, not measured before/after results. Keep the display on a stable support, outside the camera frame, and change one thing at a time.
| In your preview | Try | Check again |
|---|---|---|
| One side of your face is darker | Try moving the display closer to the camera’s direction rather than far to one side. | Check whether the balance suits you. Ambient light and camera exposure may change the result. |
| Glare in glasses or a reflective surface | Try a small change in display angle or placement while keeping its support secure. | Recheck reflections and comfort; stop if you need to squint. |
| An unwanted colour cast | Start with neutral, then compare a tint against your existing room light. | Camera white balance can change the look. Warm/cool are rendered RGB choices, not Kelvin values. |
| The image keeps changing brightness | Keep room light and position steady while comparing. If your camera app provides exposure and white-balance locks, use its own instructions. | Automatic exposure can mask differences. The page cannot guarantee lux, light output or calibrated illumination. |
The slider changes rendered colours, not hardware backlight. No physical lighting measurements or matched camera photographs are claimed.
What the intensity slider changes
The slider scales the red, green and blue values of your chosen tint. At 50%, neutral becomes #808080. It changes the apparent light from the page; it does not control your display backlight or provide a measured percentage of light output.
Panel settings, room lighting, camera exposure and white balance affect the final look. There is no camera access or automatic exposure adjustment here.
A display has limits
This is not a calibrated video light or a substitute for colour-critical lighting. Try it in your actual call or photo setup before relying on it. The warm and cool presets are visual choices, not Kelvin measurements.
Need exact white with no adjustments? Open the plain white screen. To inspect shading on the display itself, use the guided screen test.
