I love all kinds of finishes. I love colors in general. I do think certain combinations of colors clash in unpleasant ways, and I am personally not overly fond of "boutique coffee table basses" with highly-figured wood, etc. (Although there are exceptions to this--I dig the look of early Alembics, for instance.)
But most of your relatively common colors--pretty much any Fender finish--the metallics, the pastels, even sparkle/glitter/metalflake jobs--I like.
However, I've noticed that in my life whenever I have bought a guitar or bass in colors like that, I tend to part with it fairly quickly.
I know it may be very boring, and I DO like seeing funkier/flashier colors on other people's instruments, but for ME, the guitars and basses I tend to keep longer and never get tired of are either off white, black, natural or sunburst.
That said, the last bass I bought (it's in layaway) is dark blue. But I think it's a keeper. If I get tired of the color, I'll just refinish it.
