A METHODOLOGY FOR POPULATING DEFAULT COLOR MAPS

Abstract

A standard for using colors in computer graphics systems is proposed. A key aspect of this proposed standard is to allow two different levels of access to colors. At the first level, colors are selected from a standard list. To draw a red line, for example, a user would simply issue a command that says, in effect, draw lines in color number two. The association between two and red comes from a standard color map. At the second level, colors can be precisely chosen or mixed from a three-dimensional color model. The first level is a strict subset of the second level. Users can access colors at the level appropriate to their experience or application need and can move from one level to the other as required. The keystone of this proposal is a method for defining a device-independent default color
