Hydra Miniatures Robots

Found a rather nice blog called Laughing Ferret.  If you want to see gorgeous figures with great paint jobs, definitely check it out.

The figures below are from hydraminiatures.com and have an absolutely killer retro color scheme that Laughing Ferret brought to life.  Think of 1950's colors that make these figures pop. 

Any suggestions on how to come close to this green/blue color?
