My high light one is blue with a maroon base and in the shadows… the regular lighting is maroon with yellow tips and frag rack cooking is neon greenThat's the colors it has. Different lighting and different parameters bring out the different colors. One with blue is lower light I think? Yellow should be tips and growth (my growth edges are green). There is also a Red Cadillac that's not a Reef Raft but I don't know if it's a different acro or just a color shirt of the original Pink Cadillac.
