It's a Holographic finish with a black burst edge. Which means when no light is shining on the bass it looks black, but as soon as it's hit by a light source it reflects a rainbow of colors. The cool part is that the colors change depending on what angle you view it from and the angle of the light. So if you're moving around stage or if lights hit you from different angles or audience members change their viewing angle the bass color is constantly changing, It basically puts on its own light show. I get more comments on the looks of this bass than any bass I own. Here's a couple of pics from different angles, note the color shift...
On a side note the bass did cause a bit of a dust up once between two very inebriated girls, one of whom swore the bass was green and the other calling her an idiot because it was clearly blue and red. They were viewing it from about five feet apart on the dance floor. I calmed them down by telling them it was a mood bass and that the color would look different to each person depending on their mood. Drunk people can be pretty gullible.
