RColours by Brian Taylor

RColours converts the colour bands commonly found on resistors into the value of that resistor or it converts a given value into the colour bands that would be used to represent that value. 3 and 4 band representations are supported and the user can switch between the two to compare the result. The value is displayed or can be entered in the industry standard 1K2 style. The colours are displayed on a picture of a resistor as well as named.
