[Haskell-cafe] Looking to check on some capabilities of Data.Colour

I was wondering if Data.Colour supported Double-valued colour components > 1.0 or less than 0. I'm looking to create an HDR image processing library, and Haskell has one of the most extensive and correct colour models around, thanks to Russell. With 16bpcc or 32bpcc images, however, I need to be sure to be able to correctly calculate colour values that fall outside the usual [0.0,1.0] gamut. Does Data.Colour support this functionality? -- Jeff
