1. A method for processing a pixel, comprising:
- converting the pixel'"'"'s color space from Cartesian coordinates to polar coordinates;
determining whether the pixel lies within a 3-dimensional region described by a set of region parameters;
applying a correction factor based upon the pixel'"'"'s location in the 3-dimensional region; and
converting the pixel'"'"'s polar coordinates to Cartesian coordinates.

Abstract
A method, system and apparatus for color management that directly acts upon the hue, saturation, and luminance value of a pixel instead of its U and V value. Additionally, instead of dividing the color space into uniform areas, the color space is divided into multiple user-defined regions. The detection of a pixel is based on its hue, saturation, and luminance value, so a single set of values can define the correction for an entire hue.
