Spline-based color sequences for univariate, bivariate and trivariate mapping

Alternative models that use B-spline curves and surfaces for generating color sequences for univariate, bivariate, and trivariate mapping are introduced. The main aim is to break away from simple geometric representation in order to provide more flexibility and control over color selection. This facilitates the task of constructing a customized color scheme for a particular map. The author gives a brief description of existing color schemes and their characteristics, and provides some background for B-spline curves and surfaces.<<ETX>>
