Royal, Robot, and Zombie are all colours that have nice accessories most of the time. The Ogrin and Lutari are the only pets that do not come in White. It is one of two pets that cannot be painted Brown (the other being the Chia). Maractite, Woodland, and Transparent could all be very pretty (or, at least, pretty interesting). Relic, the other new colour, might or might not work. Halloween would be a bit out of place this time of year, but could still happen while I'm really not sure what they'll do for Maraquan (though I'm hoping it'll reference Capricorn).
Ice is a wintery colour, though it also tends to be hit or miss. Silver and Gold go with an old Christmas song but I don't recall both ever being released at the same time. Skunk and Camouflage could be interesting if done well. Jelly, Strawberry, and Biscuit are also potentially good colours. Speckled (and possibly Striped) could also have potential while Disco is a bit sketchy when it comes to quality. Speaking of Sketch, both it and Darigan lost a lot after the revamp, as did Sponge and Grey. Split and Invisible are generally not inspiring. Custard and Snot are Custard and Snot.
Thoughts, hopes, desires?
