color-named

Require (where possible) or disallow named colors.

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

This rule ignores $sass and @less variable syntaxes.

Options​

string: "always-where-possible"|"never"

"always-where-possible"​

Colors must always, where possible, be named.

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.

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); }

Optional secondary options​

ignore: ["inside-function"]​

Ignore colors that are inside a function.

For example, with "never".

The following patterns are not considered problems:

a {
  color: map-get($color, blue);
}
a {
  background-image: url(red);
}

ignoreProperties: ["/regex/", /regex/, "string"]​

For example with "never".

Given:

["/^my-/", "composes"]

The following patterns are not considered problems:

a {
  my-property: red;
}
a {
  my-other-property: red;
}
a {
  composes: red from './index.css';
}
