chore(TS): Color

[ShaMan123]

Color class

I have created a patch index for util so we can start importing from there

I don't like that the history isn't kept between src/color.class.ts -> src/color/color.class.ts so I think we should open a PR that only moves the file and then merge this one and do that in future PRs

EDITED
Merge #8116 BEFORE this PR, update from master and merge this

let's not use default exports, is a mess when we mix default and named exports.
Let's merge this PR. But in general this kind of extraction i think is actual code more than a bunch of import/exports that goes away at rollup time. I would like to use named exports only unless we have some kind of concerns internally.

[ShaMan123]

For sure
I want named exports as well.
Just for hacking the build

[ShaMan123]

well maybe we should remove this line
nothing should use it
