7. A non-transitory computer-readable storage medium (NTCRSM) comprising a set of instructions executable by a processor resource to:
identify a range of colors around a pixel region;
compare the range of colors around the pixel region to a color within the pixel region with respect to a perception threshold that represents a perception tolerance associated with the color within the pixel region;
determine a modification of the color within the pixel region based on the range of colors around the pixel region and the perception threshold; and
cause a display to present the pixel region in a modified color based on the range of colors around the pixel region with respect to the perception threshold.
