since i just posted about a bug that is probably related to the wire recoloring ability :

blue and green are relatively dim colors and red and yellow are relatively bright. thus i would like to use red and yellow for highlighting them while constructing, and blue and green to "hide" wires otherwise, but currently i can't freely select the colors and only have the choice between two bright/dim pairs, selecting either the pair red/green or blue/yellow.

it would be nice to have a dropdown option listing all six possible combinations of wire colors to select from (or even all 12 when including the distinction which one is first to replace red and which one second to replace green).
