1. A method comprising: transforming a first plurality of color components of a first visual color image into a modified brightness component using a first transformation, wherein the first plurality of color component are color components in a first color space, wherein the modified brightness component is a brightness component of a second color space, wherein the second color space includes a plurality of chromatic components in addition to the brightness component, and wherein the first transformation is different from a second standards transformation that transforms all color components of the first color space into a brightness component of the second color space; transforming all the color components of the first color space into the chromatic components of the second color space; and transforming the modified brightness component and the chromatic components of the second color space into a plurality of new color components in the first color space of a second visual color image, wherein the plurality of new color components includes all the color components in the first color space; transmitting the plurality of new color components to a device, wherein the second visual color image has enhanced contrast in comparison to the first visual color image.
