A World Wide Web (WWW) based tool for the learning of color models is presented along with a methodology of use. The system was developed in Java, allowing its remote use and a high degree of interaction with the user. It shows two color systems (RGB and HSB), users choose their position relative to the solids that define the system and positioning control points, define the section of the solid to be designed. Both the system and the methodology are desktop-oriented, and are low-to-moderately demanding in terms of both hardware and software.
