Can we document the color variables used here.

[hgup]

If I want my whole app to benefit from the reusability of color variables that are being used by the tremor UI kit, I will need to know what each name is being used for.

For example, on digging into the node_modules folder for a button component, I found the following style rule:

• for primary button use brand- prefix
• for hover effects use -emphasis suffix
• for the text content use -inverted suffix

In the same manner, there may be several rules (or atleast basic conventions) that dictate what a particular color variable is being used for. Me, as a user would like to see it documented in the theming region, so that I know (when I am making my custom UI), what color variables to use for which component.
