A display apparatus is provided. The display apparatus includes a display panel comprising a plurality of pixels, a panel driver configured to drive the display panel, a storage configured to store information regarding a color gamut of each of the plurality of pixels, and a processor configured to determine a target color gamut of each of the plurality of pixels so that a difference in color gamut from at least one adjacent pixel is equal to or less than a predetermined threshold value, and to drive the panel driver for each of the plurality of pixels to have a grayscale value based on the target color gamut.
