chore: rename Complete to CompleteColor

[meowgorithm]

This revision renames Complete to CompleteColor and CompleteFunc to CompleteColorFunc. Out of context, Complete is too ambiguous, particularly because the scope of Lip Gloss is beyond color.

Should we also rename LightDark to LightDarkColor? IMO, these two types don't really represent colors but more like color helpers.

@aymanbagabas I think LightDark is fine as-is because it implies color (or, at least, luminance). I'm fine if Complete is something other than CompleteColor but we need something beyond Complete to make it more specific.

CompleteColor to me still doesn't convey the full purpose/intent, only helping convey that it's related to a color. Thoughts on something like ResolveColor (ColorResolverFunc for the func type)? "resolve" indicates it is the final result of some computed logic, and that might hint that a user can hook into that resolution logic to change it.

Some other thoughts, in case we're still not 100% on anything:

• AdaptiveColor
• DownsampleColor
