1. An apparatus to reproduce a preferred color, the apparatus comprising: a region judging unit to judge whether pixels of an input image are included in one or more preset color regions; a target color determining unit to determine a representative value of the input image and a final target color of a conversion-desired color region, wherein the representative value is a value included in the conversion-desired color region, and the final target color is determined by using the representative value and a reference target point assigned to the conversion-desired color region; a color converting unit to execute a color conversion of the pixels in at least one conversion-desired color region, including the conversion-desired color region, among the one or more preset color regions that include the pixels; and an output unit to output an image formed by the color-converted pixels; wherein the preset color regions are defined prior to initially loading an image for display, color conversion of one color region may supersede the color conversion of another color region, and the color conversion is performed by moving the pixels close to the final target color.
