The color function can now include a number of flags like color(value, flag-1, flag-2, ...). override and set-theme flags allow passing a color. no-warn suppresses the warning.

Rewrote this to restrict the false pass-through to set-theme only — this allows the color() function to be used when setting the theme token (since theme tokens can be false).

Improves error handling. We can't check against the theme colors when we're setting them, so setting the set-theme flag bypasses this check
