An automated method for proofing a page for color discriminability problems includes converting a first color of a first object appearing on the page and a second color of a second object appearing on the page to coordinates of a color naming system. The method includes identifying a first color name of the first color and a second color name of the second color based on the coordinates. The method includes identifying whether the first color and the second color are discriminable based on the first color name and the second color name.
