Re-coloring Images for Color Deficient Viewers

More than ten million Americans have color-deficient vision.  The impact of this disability is broadly felt, and its importance is growing, as our society increasingly depends upon the display of color images for information and education. Nevertheless, creators and designers of images for color displays rarely account for the potential loss of information that may be experienced by color-deficient observers.

In a recent paper [1], which was awarded the Günther Enderle Prize (Best Paper, Eurographics 2005), we describe an algorithm for automated re-coloring of images to preserve information for color-deficient observers.  To see examples of the application of the algorithm, click on any of the above images.
