Colors are commonly represented in terms of the absolute magnitude of their coordinates in a specified color space, and differences between them in terms of the distance between their locations in that space. This Demonstration creates images for convenient visual comparison of two colors based on the numerical values of their CIE Lab or RGB coordinates. It can also translate continuous changes in any coordinate into an image that reveals visually how the perceived difference grows or diminishes.
