Hmmm, they'll have to start designing sets differently then. You'll often have the same element in more than one colour in a given set. Obviousl the colour won't matter to the person constructing it but to anyone viewing it, it certainly would.
Modified elements would probably need to be fairly descriptive:
- "place the 1x2 with the cylindrical protrusion"
- "place the 1x2 with the cylindrical depression".
- "place the 1x2 so that the rectangular textured masonry surface is facing out"
