Nearly all machine-to-human communication is visual. The ability of the human designer has the greatest influence on the effectiveness of this communication. In scientific visualization, color placement performs an essential role in differentiating and associating visual data ( Tufte 1990).
The number of factors involved in color placement can cause the task to be overwhelming ( Silverstein 1987). Many programmers have attempted to dispose of the problem by forcing users to use the same color scheme in every situation, by limiting the user's palette, or by providing default colors.
In visualization, these solutions have had very limited success. Color schemes that work well for one particular visualization may be completely unsuitable for another. Users who encounter problems with color placement find that they either have to accept the colors provided or quickly become experts in color placement. Applications desperately need color placement support for visualizations.
Color balance means the relative conspicuity of each part of a design. Although color balance is clearly influenced by other design factors, such as shape, form, etc., we have chosen to ignore these for the time being and attempt to work with only the color placement aspects of design.
We propose the following problem for color balance support. On an interactive color placement system, allow the user to place colors on flatly colored, two-dimensional visualizations. Allow the user access to real-time
