I like the idea that color.equals(Color.web(color.toWeb())).

How do we determine which format is going to be returned by toWeb? I think it should be consistent (ie: pick one to use all the time). Otherwise it becomes arbitrary and folks cannot easily parse the results or do what they need with it.

Why remove the #? What is the use case for toHexString()?
