IMO, statics are simplified equivalents of singletons. They grow from
globals - functions or variables. There is not much more.
I would suggest statics
- when you need global method, property or function
- when you need global variable
- when you need singleton, which exists during whole application lifetime

I found it easier to code singletons using statics. Excellent examples -
such classes like SystemInformation or Environment.

But Joshua was talking about using instances of Color, where those instances are singletons (well, flyweights is probably the right term when there are several of them), exposed in static final fields on Color, and the class is written in a certain way, which i take to mean having a private constructor, not creating any instances other than those in the statics, and implementing readResolve. ...
