Color needs to be easier to work with

[zshall]

The current color system needs to be easier to work with.

At a bare minimum this color grid on the docs website should copy the selected color to the clipboard when it's clicked.

Also we need bg-black, text-red, etc. Nobody wants to remember color E2 is teal or B3 is yellow. Not every single color needs an alias that makes sense but we could add -dark or -light variants to the most common colors...

• red
• yellow
• yellowgreen
• green
• bluegreen
• teal
• purple
• pink
• black
• gray
• white

We'd put -d at the end for dithered.

Also wonder if it's possible to get away from using !important.
