They differ from battery to battery. The first one I got, the colors where pretty well separated and yeah, looks a little fru-fru. The second one, the colors are a little bit more smooshed together, and it looks more like a chromey golden bronze with some purple, blue and teal at the end. But I don't think you'd be able to request one or the other - you just take your chances.
And of course, if you glue on some SS9 rhinestones at the bottom to mark the settings (because you really can't read them), ...
But I love SI's yella too. I call that one my Bruce Lee battery, all decked out with a black EVOD and a Yin Yang charm. This is always my first color whenever SI comes out with a new battery type.
The orange and neon/lime green have their own personalities too.
