LGTM, but I have a couple of questions due to my lack of understanding on how hex colors are parsed 😅

When Sass parses #abc, does it internally store it as if it parsed #aabbcc?

Currently #abc == #aabbccff returns true, per the spec changes this will now return false, or no?

And if it now returns false, is this covered by the false/legacy/same_space/rgb/one_none test?

All colors are stored as four floating-point numbers (the three color space channels and the alpha channel) as well as the color space name. #abc, #aabbcc, #aabbccff, and rgb(170 187 255) all share the same internal representation, and so are mutually == to one another. We test this in the tests for color parsing and constructor functions; here we can safely assume that the internal representations are the same, and that we only need to verify checks for that expected representation.

Out of curiosity, is color.same(#abc, #abcf) covered by true/same_space/none_and_zero or by true/different_space/no_none/input?

#abcf isn't a color. Do you mean #abcdef? Those would be different colors, so they'd be under false/.
