word order - White-orange or orange-white? Which color comes first?

When referring to something, (electrical wires, in my case) and it is half white and half other color, do you put White or the other color first?

I want to describe the color of these wires as ONE word/phrase. They are all half white and half other color (orange, green, blue, brown, etc).

So would I say "Please grab that white-orange cable" or would I say "grab that orange-white cable"? I would imagine you put whichever color is more first, but the white and orange are equally divided. Not sure if what I'm saying makes sense...
