For a softer, warmer light, pick a pale yellow with Your colour and turn the Brightness slider down a little.
About the Yellow Screen
This page is a plain yellow screen. Press Full screen and your whole display turns yellow — no buttons, no text, nothing else.
Yellow is a warm, cheerful light for a room, a photo or a party. It is also a useful screen test: a yellow pixel is made of the red and green parts only, so it shows faults that a plain white screen can hide.
It runs in your browser. Nothing is installed and nothing is sent anywhere.
Features
- Opens yellow — the page is already bright yellow, one click for full screen
- Any yellow — use Your colour for a pale, warm or golden yellow
- True full screen — no menus or text on top of the light
- Brightness slider — make the yellow softer, down to 10 %
- Keep the screen on — the screen does not go dark while the light is on
- Other colours — white, black, red, green, blue, pink or any colour you pick
What people use a yellow screen for
- Warm light. A yellow screen gives a warmer light than white — nice for an evening room, a cosy photo or a video call with a softer look.
- Mood and party light. Sunny yellow for a party, a game or a theme photo.
- Photo effects. Hold a phone with a yellow screen near a face or an object for a golden glow.
- Screen test. On yellow, the blue part of each pixel is off. A pixel with a stuck blue sub-pixel shows as a white or pale dot. A pixel with a broken red or green part shows as a green or red dot.
- Check for a colour tint. Patches that look more green or more orange than the rest show an uneven screen.

Frequently asked questions
How do I make my screen yellow?
Press Full screen on this page. The whole display turns yellow. To give your whole computer a warm tint instead, turn on Night Light (Windows) or Night Shift (Mac).
Why is yellow good for a screen test?
Yellow uses only the red and green parts of each pixel. So a blue part that is stuck on shows up as a pale dot, and a broken red or green part shows as a coloured dot. White and black alone can miss some of these.
Is yellow light better at night than white?
Warm light has less blue than white light, and many people find it calmer in the evening. For the gentlest light in a dark room, use a dim Red Screen.
Is it free?
Yes. It is free, with no sign-up and no download.
