How to use it
- Click the yellow box above, or press F.
- The whole screen turns yellow. Move the mouse or press an arrow key to see the controls hint.
- Click anywhere or press Esc to go back.
On an iPhone the browser keeps its address bar, so the color fills the page but not the very top strip. Turn the phone sideways or scroll a little to hide the bar.
What a yellow screen is for
- Warm light. Light yellow is a softer, warmer alternative to a white screen.
- Pixel check. Yellow lights the red and green parts of each pixel. A pixel that looks red or green on yellow has a fault in the other part.
- Backgrounds and signs. Bright yellow is easy to see from a distance.
