A color blindness-simulating digital image is generated from an original digital image. Wireframe versions of the original digital image and the color blindness-simulating digital image can be generated. A comparison digital image between the color blindness-simulating digital image and the original digital image is generated, such as by comparing the wireframe versions of the original digital image and the color blindness-simulating digital image to one another. The comparison digital image is indicative of the extent to which a color-blind person is unable to distinguish features within the original digital image.
