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 held constant and the colour bands altered to suit).
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 being named in the drop-down dialogue boxes that can also be used to select the colours when converting to the value.
Informative dialogues can be opened to provide explanations of the tolerance band colours and the temperature coefficient colour-band if it exists. A help file is also included.
