Royal is a good colour for clothing, and for TNT this means being able to do two colours for the price of one. Zombie could be another cool colour for them. Tyrannian could be nice if done well though, given the appeaance of Darigan, it's hard to imagine what they'll do for Tyrrannian. So far the Acara is the only pet to come in Woodland, so it would be interesting to see if the Ruki become the second pet. Relic hasn't been done in a while either, and it may actually work well with a Ruki body. Orange is a very basic colourfill and both Gold and Silver tend to be as well. Striped, Skunk, or a really well done Spotted can be cool patterns. Jelly and Strawberry have shown potential (Strawberry in particular has been pretty well-thought-out lately). Snow is an iffy colour that can be done well but is often done only mediocrely. Ice, Glowing, and Split tend not to be anything to write home about. Sketch and Sponge lost a lot of their uniqueness after the revamp, as did Gray. Invisible and Snot are Invisible and Snot.
