The coordinates within the parenthesis provide, in order, the relative values of red, green, and blue light. The number in each position ranges from 0 (no color added) to 255 (100% color added). This range was chosen because it is the most commonly used in computer color selection dialogs. (The

Therefore, Knowledge has chosen standard ranges for the coordinate systems, so as to have consistent coordinates in all color articles. This article describes the chosen systems and provides instructions for conversion to other ranges which might be needed by particular color environments.

The coordinates within the parenthesis provide, from left-to-right, the relative values of cyan, magenta, yellow, and key. The number in each position ranges from 0 (no pigment used) to 100 (maximum = 100% pigment coverage).

This coordinate system is problematic, because programs that accept this system use several different ranges of numbers on input. Some of these are listed in the table below.
