How To: Create colors in ArcView using CMYK and HSV values with an extension.
ArcView stores all color information as RGB color values. Colors, which are equivalent to CMYK or HSV colors, can be created by applying a mathematical conversion. The following instructions provide information on downloading, loading and using the 'HSV, RGB or CMYK Color Creation' sample extension. This extension creates an RGB color based on CMYK and HSV values you input. The new color is added to the color palette.
