Ok, I\'ll give you my honest opinion, but I am a bit biased since I am a freelancer for Reaper and I have half of the paint set (getting the other half this weekend).
There are 216 colors, all part of triads that include the shadow, midtone and highlight, though you have a wide range to work with and can mix your own colors if needed.
The RMS paints are already formulated with \"gunk\" in it so all you have to do is add a little bit of water to thin it out. you don\'t need to add any more flow improve, retarder, etc to the paint as it\'s already in there. Not to mention Reaper actually cares about their consumer base, so if you have any problems with the paints they will usually work with you to figure out if they need to be replaced at no extra charge.
