Use toolFrequently asked
What HEX formats are accepted?
#RRGGBB and #RGB shorthand are both accepted. Hash prefix is optional.
What does HSL stand for?
Hue (0–360°), Saturation (0–100%), and Lightness (0–100%). HSL is often easier to reason about than RGB because you can adjust brightness and saturation independently.
Does the converter support alpha/opacity?
Not in the current version. HEX, RGB, and HSL conversions assume fully opaque colours. For alpha, add an 'a' suffix manually: rgba(r, g, b, a) or hsla(h, s%, l%, a).
