Open a selected solid color in a browser full-screen overlay for viewing, cleaning, or visual checks.
Loading the tool… JavaScript is required for processing on your device. The instructions and examples below are available without JavaScript.
How to use it
Choose a color (white by default) and open it full screen. Click or press Esc to exit.
Good to know
Brightness comes from your display settings. Turn it up for a brighter light.
Choose a solid background
Select White or another swatch, or use the Custom color picker, then choose Open full screen. The overlay shows that one color. Click it or press Escape to leave; if the browser grants full-screen access, it also exits when full-screen mode ends.
For display cleaning, turn the screen off or follow the manufacturer’s cleaning guidance before touching it. Use the white view to make surface dust easier to see, not as a substitute for cleaning instructions.
Brightness comes from the device
The tool draws a color; it cannot raise screen brightness, override night mode, or control an external monitor. A browser or operating system may refuse full screen, dim the device, or show system UI. Color appearance varies with the display and its settings.
