# Objective
- Fixes#13214
## Solution
Delegates to internal type when possible, otherwise uses
`ChosenColorSpace` as an intermediary. This _will_ double convert, but
this is considered an acceptable compromise since use of specific colour
types in performance critical colour operations is already encouraged.
`ChosenColorSpace` is `Oklcha` since it's perceptually uniform while
supporting all required operations, and in my opinion is the "best" for
this task. Using different spaces for different operations will make
documenting this double-conversion behaviour more challenging.
## Testing
Changes straightforward enough to not require testing beyond current CI
in my opinion.

## Changelog
- Implemented the following traits for `Color`:
- `Luminance`
- `Hue`
- `Mix`
- `EuclideanDistance`
- `ClampColor`
- Added documentation to `Color` explaining the behaviour of these
operations (possible conversion, etc.)
