Claim One:
1. A computing system comprising: one or more processors; memory storing computer executable instructions that, when executed, cause the one or more processors to perform acts comprising: receiving an image being created by a designer; generating a gradient map of the image; generating a simulated colorblind view of the image, a colorblind gradient map of the simulated colorblind view, and a full colorblind gradient map of the simulated colorblind view; determining, for each of multiple pixels of the image, information loss between the non-colorblind gradient map and the colorblind gradient map; determining a color space value for each of the multiple pixels from the full colorblind gradient map; locating inaccessible points in the image based at least in part on the determined information loss and the determined color space value; locating inaccessible regions based at least in part on the located inaccessible points; and identifying the located inaccessible regions in the image to the designer.
