The maths is ancient, simple enough for a fine art student like me to  
understand, and is in any good graphics textbook (e.g. Foley & Van Dam).

You just need to implement it wherever you use colour. Which for  
projects the size of Gimp or Inkscape is not a simple task. Plus SVG  
doesn't support it at all and you need colour management to get the  
colours looking bearable on different devices. It gets less simple  
very quickly. :-)
