In Blueprints, please colour-code tier-2 Belts/Pipes

I often make the mistake of selecting the tier-2 Flat Transport Belts or U-Shaped Transport Belts when making a Blueprint when my build warrants only the much cheaper tier-1, and sometimes I don't notice my mistake until it's too late, and I've wasted a lot of valuable resources on a faster Belt than I needed, possibly a long one.
Furthermore, tier-2 Belts consume more electrical Power, so there is all sorts of incentive to not use them when you don't feel the need for the speed.
I'd really like at least an UI option that I can toggle, so that tier-2 Belts (Pipes too, ideally, although they don't consume electricity) are shown as a different colour from the "standard transparent light blue", so that I'm given a visual cue when I've used the wrong type of Belt.

There is a suggestion to color pipes that is already planned. Perhaps this should be rolled into that one?
