Common questions about screen utilities, color temperature, dead pixels, and monitor care.
How do I create and share a custom full screen color URL?
Enter any 6-digit Hex code (e.g. #FF5733, #00FF00, #7928CA) or use the RGB/HSL sliders. The page URL will automatically update with your custom code (e.g. /custom-color?hex=FF5733). Click 'Copy Shareable Link' to send it to anyone!
Can I download wallpapers of my custom color in 4K or 8K?
Yes! Once you tune your custom color, scroll down to the 1-Click Wallpaper Generator to export exact-fit wallpapers in Full HD (1080p), 2K, 4K UHD, 8K Ultra, Ultrawide 21:9, or Mobile 9:16 format.
Does the custom color screen support keyboard shortcuts and screen wake lock?
Yes! Press 'F' for Fullscreen, 'Space' to toggle HUD controls, 'Esc' to exit, and keys 1-9 for instant brightness adjustment. The built-in Screen Wake Lock API prevents your screen from dimming or sleeping while active.
What color formats are supported?
The tool supports Hex codes (#RRGGBB), RGB (0-255 values for Red, Green, and Blue), and HSL (Hue, Saturation, Lightness) with real-time bidirectional synchronization.
