    SIGGRAPH Course Notes

    A Survey of Color for Computer Graphics Maureen C. Stone StoneSoup Consulting Course 4 SIGGRAPH 2001 August 12, 2001 A Survey of Color for Computer Graphics SIGGRAPH 2001 Description This course will survey color disciplines relevant to Computer Graphics ranging from color vision to color design. Participants should leave with a clear overview of the world of digital color, plus pointers to in-depth references on a wide range of color topics. For each topic, a brief overview and pointers to further informa- tion will be provided. For most topics, I will suggest a standard reference book or two, augmented by published articles as needed. The course should be of value both to those seeking an introduction to color in computer graphics and to those knowledgeable in some aspects of color who wish to get a broader view of the field. Presenter Maureen Stone is an independent consultant working in the areas of digital color, large format displays, web graphics, interaction and design. Before founding StoneSoup Consulting, she spent 20 years at the Xerox Palo Alto Research Center where she attained the position of Principal Scientist. She has over 30 published papers plus 12 patents on topics including digital color, user interface technology and computer graphics. She has taught in SIGGRAPH digital color courses organ- ized by William Cowan (SIGGRAPH '89) and Charles Poynton (SIGGRAPH '97), and first presented this survey course at SIGGRAPH '99. She has a BS and MS in Electrical Engineering from the University of Illinois, and a MS in Com- puter Science from Caltech.
