A method of changing a pixel color includes determining whether a chrominance of a pixel is in a preference chrominance area, where the preference chrominance area is defined as a conic section in a two-dimensional chrominance plane and an eccentricity of the conic section is not greater than 1, and changing the chrominance of the pixel to a preference chrominance to generate a preference pixel when the chrominance of the pixel is in the preference chrominance area. Therefore, the method may set a preference chrominance area in a simple manner, and hardware for setting the preference chrominance area may be easily implemented.
