What Is a Color Screen?
A color screen fills your display with one solid color. It is useful for checking a monitor, finding stuck pixels, creating a colored light source, previewing background colors, or showing a clean color on a projector or second screen.
How to Use the Color Screen Tool
Choose a preset color or enter a HEX value, then open the full-screen view. Use white, black, red, green, and blue to inspect common display issues, or pick a custom color for lighting and background checks.
Frequently Asked Questions
Can I use this to check for dead pixels?
Yes. Open a full-screen white, black, red, green, or blue screen and look for pixels that stay dark, bright, or the wrong color.
Does the tool upload anything?
No. The color screen runs in your browser. It does not upload files or require an account.
Can I enter my own color?
Yes. Use the color picker or type any valid HEX color such as #ffcc00, #111827, or #ffffff.
Why does full screen need a click?
Browsers only allow full-screen mode after a user action, so the tool opens full screen when you press the button.
