Usermodel style color values are undocumented despite having specific limitations.

It appears that for color, the UserModel, minimally requires the values to be valid hex colors only. It will not allow named colors, css rgb(...) specifiers or others. In sheetui I allow both of those currently so would need to either convert them to hex formats before setting the styles or use the lower level model. Is the hex only approach in UserModel intentional?

I would be willing to prepare a PR to add some checking for other valid css values or minimally add documentation to the APi so consumers know what to pass in.

Hi @zaphar, give me a few days to think about this. So Excel saves them in hex format (I think!). That doesn't mean we have to. I think we definitely should accept named colors,, rbg, etc.

Certainly. It's not super difficult to do the translation on my end so either way I can still work with it.
