Consider replacing color names in theme with names specific to characteristics.

## Description

There are some color attributes like `charts.cyan` or `badges.green` which are color specific. We should discuss with @shawnbranstetter is it makes sense to rename them to make the name independent of the color.

Example, what if we want to use a slight different color than cyan for the current color of `charts.cyan`? In this case we would have to rename the key as well.
