Claim 7:
8. A method performed by a processor of an electronic device, comprising:
outputting a user interface for display on a display device, wherein the user interface comprises:
an element configured to receive user input specifying a first color value for a first color, the first color comprising a first single reference color;
an element for specifying at least one desired characteristic of an unspecified desired color relative to the first color, the desired color comprising a second single color, wherein the at least one desired characteristic is one of:
a same RGB ratio as the first color but with a different specified relative luminance than the first color,
a same RGB ratio as the first color with a specified contrast ratio separation from the first color, and
a different RGB ratio than the first color with a same relative luminance as the first color, and

receiving via the user interface user input specifying the first color value;
receiving via the user interface a selection of the at least one desired characteristic;
based on the received specification of the first color value and the selection of the at least one desired characteristic, determining with the processor what color is the desired color that has the selected desired characteristic relative to the first color; and
outputting the desired color on the user interface, as an individual second single color, beside the reference color, as an individual first single reference color.
