Color in Information Display Principles, Perception, and Models Maureen C. Stone StoneSoup Consulting Course 20 SIGGRAPH 2004 Description Color is a key component of information display that is easy to use badly. As a result, Edward Tuftes key principle for color design is do no harm. While inspired color de- sign is an art, the principles that underlie good color design have their roots in human perception and a deep understanding of the color properties of different media. Over the last decade, there has been significant progress towards providing computational mod- els for color perception. Similarly, there has been substantial research and engineering work that has made it easier to predict and control color in digital media. Taken to- gether, these provide a foundation that should enable the algorithmic application of color that is robust and effective, if still not inspired. This course will survey the topics that support such a goal, and will provide pointers for further in-depth exploration. Topics include: Principles for the use of color in informa- tion display; principles of color design and color harmony; ways to numerically define and transform color, including visual, perceptual, aesthetic, and media-specific color spaces; color management systems and their application; color appearance fundamen- tals. The course will include an overview of some relevant research, including: automatic generation of color scales, algorithms for mapping names to colors, models for color blindness, and computational models for color appearance. Prerequisites This course should be accessible to all SIGGRAPH attendees able to understand basic scientific and mathematical presentation (simple graphs, diagrams and algebraic equa- tions). Intended Audience This course is intended primarily for engineers and researchers involved in the devel- opment of systems and algorithms for information display, which includes visualization, illustration and
