FWIW, themes by color grouping would be great for me. I really enjoy going through our styles but I'd adore seeing them broken down by groupings like that. I think the Accessibility categories are just good in general, but the Color categories would be useful for me!

As to the implementation side of things, I will leave feedback on that to fu or someone. But if you have specific questions I'm always happy to comment.

ALSO, fwiw, it seems like this might belong in dw_dev or dw_styles or something. I'm not sure about putting it here in a training community? (Although to be fair, this community is loosely defined so it's fine, I'm just noting.)
