As far as I know, you can't. It needs machine representable types, such as
Int, Double, Char, etc. But making a tuple of three UArray Int Double may
help.

Thanks for help. I did some tests with UArray and it does the trick. The problem remaining is, how to implement UArray Int (Double, Double, Double)? UArray source code is far too cryptic for me.

pixelArray :: Array Int Color
it's boxed array which means that its elements are stored as thunks computed only when you actually use them. try UArray instead:
