The apparatus for correcting a color reproduced by a video device according to peripheral brightness includes: a lookup-table-creation unit which creates a lookup table based on saturation of the video device and brightness of peripheral conditions; a color-correction unit which corrects the color reproduced by the video device according to the created lookup table; and a color-error-compensation unit which compensates for color error resulting from correction of the color. The method of correcting a color reproduced by a video device according to peripheral brightness includes: creating a lookup table based on saturation of the video device and brightness of peripheral conditions; correcting the color reproduced by the video device according to the created lookup table; and compensating for color error resulting from correction of the color.
