Awesome, what a cleanup 👍
I have mixed feelings about removing the 'value' from the color picker element. It's currently not used in de our context of the lights. But removing it reduces the reusability of the element (for example to pick interface colors). But whatever, it's easy to put back in :)

Thinking further:
The color picker was designed with reusability in mind, so it would take and return both hsv and rgb color objects. (so it could also be used to pick colors for things where we would need a rgb value, theming/customizing for example) I know we don't use that currently. But the rgb code is not really in the way, and execution is limited by throttle.

Well right now at least it didn't have any way to actually select a value, it was just hard-coded to 100%. We'd need a new UI element to properly select a value if we wanted to use it for that. That would definitely make it more reusable though.

Also certainly not opposed to adding RGB back to this component if we want to use it, but I'd rather not ship unused code since anything included here contributes to the size of the frontend build clients need to download.

Agree on your points.
We'll just add it back in if needed. (long live version control)

Didn't realize we ran into merge conflicts here. I'll get this branch up-to-date tonight.
