I would appreciate any information related to the conversion from YIQ to RGB color value specification. I have a basic understanding of each system, but I have not found any literature describing how to convert from one system to another. Any information would be greatly appreciated.

The conversion from YIQ to RGB coordinates is given by [R] [ 1.00 0.95 0.62 ] [Y] [G] = [ 1.00 -0.28 -0.64 ] . [I] [B] [ 1.00 -1.11 1.73 ] [Q] for a certain (standard) set of of phosphor chromaticities. For more information see : George H. Joblove and Donald P. Greenberg, Colour Spaces for Computer Graphics, Computer Graphics 12(3). August, 1978. Alvy Ray Smith, Color Gamut Transform Pairs, Computer Graphics 12(3), August 1978. And there is a short description of YIQ in Foley and van Dam. Jan Gray jsgray@watrose University of Waterloo (519) 885-1211 x3870
