Abstract:
We propose an approach, called the Equilibrium Distribution Model
(EDM), for automatically selecting colors with optimum perceptual
contrast for scientific visualization. Given any number of features
that need to be emphasized in a visualization task, our approach
derives evenly distributed points in the CIELAB color space to assign colors to the features so that the minimum Euclidean Distance
among the colors are optimized. Our approach can assign colors
with high perceptual contrast even for very high numbers of features,
where other color selection methods typically fail. We compare our
approach with the widely used Harmonic color selection scheme and
demonstrate that while the harmonic scheme can achieve reasonable
color contrast for visualizing up to 20 different features, our Equilibrium scheme provides significantly better contrast and achieves perceptible contrast for visualizing even up to 100 unique features.
