Summary:A method and apparatus for adjusting a color in an image to a desired color value is described, wherein the method includes identifying at least a first portion of the image including the color to be adjusted; analyzing the first portion to determine a representative color value; determining a color adjustment parameter to adjust the representative color value to the desired color value; and applying the color adjustment parameter to at least the first portion of the image. The method can further include performing a desaturation of the first portion of the image before analyzing to determine a color value, and resaturating the color value; identifying at least a second portion of the image having a color value extreme to determine a color value representative of the color value extreme, and using the second portion color value in determining the color adjustment parameter; or a combination thereof.
