Colors are often used for displaying data in order to reveal their characteristics and to facilitate the task of data analysis. Much research and experimental work has been carried out to identify principles for making effective use of color and to find good computational models for constructing color schemes for representing data values. Most existing color schemes are based on simple geometric models which facilitates the computation, but do not allow sufficient flexibility for manipulating colors in a sequence. This paper introduces alternative models which uses B-spline curves and surfaces for generating color sequences for univariate, bivariate and trivariate mapping. The models provide more flexibility for interactive modification of the range of color locally in order to obtain customized color schemes for a particular map.
