I mean, her color palette isn't that bad. It's her damn proportions and odd shape, as well as the fact that she's taller than the rest. Bunny was taller, too, but that's because the PPG messed up the formula. I don't watch the show, though, so maybe there's a reason in there for being taller than the rest (and honestly that's not as bad as the other two things I mentioned).
Even if they fixed her silhouette, and even assuming a good VA and character background (which I doubt she has, given the current track record), the fact that she's even in this shitshow would counteract anything good about her. The new PPG team may or may not be be trying their hardest, but they are sure as hell are failing about as much as they can. In short, there's no reason to try adding something new and good; it's like putting diamonds in shit.

With brown hair Bliss looks more in place than the horrid DeviantArt crap they made.
