Problem

Symptoms: How do different color palettes in other graphics programs affect the color palette used in WordPerfect? Solutions: There are many different color palettes, and some graphics programs have palettes that are customized. The two basic color palettes are RGB and CYMK. RGB is the standard 24-bit red, green, and blue colors. The bits are determined by a percentage of those colors. This then determines the actual color of each pixel. For example, 100% red, green, and blue equals white. CYMK is a newer color palette based on 32 bits and the colors cyan, magenta, yellow, and black. Each color again is determined by a percentage mix. There are also gray palettes 16, 64, and 256 shades. (WPCorp does not support the 64 gray shade palette.)

Other palettes can be created as a user "customizes" the current palette and changes the fill style for a polygon, etc., to that new color. How does this affect WP? Basically when WP reads the file, it looks at the color percentage of the combined colors. It then has to choose from the 256 colors available for the closest match for that percentage. Sometimes the match is not as close. When the file is run through GRAPHCNV with /C=16 or /C=256, WP will actually do a better job of matching the color percentages.

WordPerfect will convert the CYMK or RGB color values in the graphics file to its own color palette when it converts the graphics file (when it is retrieved into WP). The WPG format supports a 2, 16, or 256 color/gray scale palette.
