What it does
Sorted CSS Colors groups named CSS colours for visual comparison. Its table puts names, RGB, HSL and hex values together, with alternative names and hue, lightness and saturation controls. The project also offers an installable web app for offline use. The web project is open source and uses the MIT licence.
If a stylesheet uses cadetblue, the table gives its hex value as #5F9EA0 alongside RGB and HSL forms. Hue tolerance helps gather nearby colours, while lightness and saturation offer other ways to compare the named choices.
Aliases are visible in the same table: aqua and cyan both use #00FFFF, and gray and grey both use #808080. These are alternative names for the same values, so they do not add different colours to a palette.
The collection covers CSS colour names, with entries such as rebeccapurple; it is not a catalogue of arbitrary custom colours. The installable web version is designed for mobile and desktop access, including offline use. Its code carries the MIT licence.
