Use color rules with mixin arguments

[stephen-oketta]

It would be nice to use the color-no-hex or color-named rules with arguments of mixins to prevent the said rules. E.g

@include no-named-color(red) would report red being used.

Generally, I'd expect any standard stylelint rules that apply to declaration values to apply to all the additional places expression-level syntax can appear in Sass, including mixin arguments, Sass variable declarations, and interpolation in at-rules, property names, and selectors.
