A problem with this is that inheritance denotes an is-a relationship.
That is, an instance of a derived object is-a base object as well.
This would not be the case with the above since a 'color' can have a
value that has no meaning for a 'light_color'.

Good idea, though.  I could use something like this -- especially for
returned status codes.
