Skip to contentHex colors (#RRGGBB) encode RGB in hexadecimal — standard in CSS and design tools.
Six hex digits after # represent red, green and blue channels (00–FF each). Shorthand #RGB duplicates nibbles. Alpha adds #RRGGBBAA in modern CSS.
Design handoff often mixes hex, HSL and OKLCH. Tentaco Color Converter translates formats locally and checks WCAG contrast against background colors.
