Generally in the CGI end of the business we have meta data that describes how to interpret the data separate from its data representation. I'd want a library to understand that separation. Floating point numbers do go >1.0 (and <0.0 once you enter abstract mathematical representations)
Personally if I ever see a HSV/HSL/etc colour space I'd avoid it like the plague as generally they are ill defined by some 'graphics' text book rather than being a true 'colour' space. This is because the approximation they make is *too* approximate for the level of adjustments we need to make.
It occurs that, there is no real reason why a Concept, once more formally defined in the language, and knowing the available models, couldnt choose a representation, by which to represent itself. regards Andy Little
