Frequently asked questions
›Alpha channel?
#RRGGBBAA or rgba() — this shows opaque only.
›Named colors?
Not supported — use HEX or RGB.
›OKLCH?
Modern perceptual color space.
›Contrast ratio?
Use WCAG contrast checker.
›Print CMYK?
Different color space, not shown here.
›Does the Color Converter store the numbers I enter?
No. All math runs locally in your browser — nothing is sent to a server, and closing the tab discards the inputs unless you save them to favorites.
›How accurate is this color converter?
The formulas match the standard textbook definition shown above. Rounding is applied only for display; underlying computation uses full floating-point precision. For regulated developer & utility decisions, always confirm with a qualified professional.
