FAQ

QHEX vs RGB?

Same color, two notations: #RRGGBB is hex; rgb(r,g,b) is decimal channels—both valid in CSS.

QWhat is 8-digit HEX?

The last pair is alpha (#RRGGBBAA); this tool supports it in the RGB alpha field.

QWhen use HSL?

Keep hue fixed while changing S/L for lighter/darker variants—often easier than editing RGB.

QContrast fails—what now?

Darken text or adjust background until you reach AA (≥4.5:1 for body text on white/black).

QIs data uploaded?

Color values are computed locally in your browser; nothing is uploaded.

Convert HEX, RGB and HSL

Front-end work often jumps between HEX (#RRGGBB), RGB and HSL. HEX fits CSS files; RGB helps with alpha; HSL makes lightness tweaks easier. When you edit one format, keep the others in sync before pasting into design or code.
