color-named

Require (where possible) or disallow named colors.

a { color: black }
/**        ↑
 * This named color */

This rule ignores $sass and @less variable syntaxes.

Options

"always-where-possible"

Colors must always, where possible, be named.

{
  "color-named": "always-where-possible"
}

This will complain if a hex (3, 4, 6 and 8 digit), rgb(), rgba(), hsl(), hsla(), hwb() or gray() color can be represented as a named color.

The following patterns are considered problems:

a { color: #000; }

a { color: #f000; }

a { color: #ff000000; }

a { color: rgb(0, 0, 0); }

a { color: rgb(0%, 0%, 0%); }

a { color: rgba(0, 0, 0, 0); }

a { color: hsl(0, 0%, 0%); }

a { color: hwb(0, 0%, 100%); }

a { color: gray(0); }

The following patterns are not considered problems:

a { color: black; }

a { color: rgb(10, 0, 0); }

a { color: rgb(0, 0, 0, 0.5); }

"never"

Colors must never be named.

{
  "color-named": "never"
}

The following patterns are considered problems:

a { color: black; }

a { color: white; }

The following patterns are not considered problems:

a { color: #000; }

a { color: rgb(0, 0, 0); }

a { color: var(--white); }
