I don't have photographic reference Andrew, but I can tell you which colour codes the new ones are.
308 - silver/light purple sides, darker purple back
309 - yellow/blue/green sides (hard to describe) with darker stripes, dark back, orange underbelly
310 - green back, dots along lateral line, lighter grey underbelly
313 - Matt yellow/green, darker back, randomly spotted upper sides and yellow belly
