Abstract
A technique developed for simulation of constrained particle systems is applied to the visualization and manipulation of colors, both in isolation and relation to each other, in one or more color spaces. Utilizing the technique, a first color can be adjusted to a second color in a first color space subject to one or more objectives between the first and second colors in the first color space; one or more constraints for adjustment of first and second colors in the first color space; and/or one or more constraints and/or objectives between the adjustment of the first and second colors in the first color space and an adjustment of a corresponding first color in a second color space to a second color in the second color space.
