Add striped color option for wire

[leannapancoast]

Could a striped color option be added to the wires? My immediate goal is to be able to do a black-and-white printout and let students still be able to tell the wires apart. A secondary goal would be higher accessibility option for those that are color blind.

Maybe also an option to change the thickness or border shape of the wires? Like a curvy or zig-zag option. Though those would be quite difficult to find in the wild.
