Colour and texture

Scientifically we know that colour and texture can control heat and sound. If we were to reverse engineer this then could we not produce more colour and sound!
If this is the case then texture and colour could mean that the efficiency of machines could get better. You notice I said get better.
There is an old saying red cars go faster white cars are cooler and black cars are hotter. No scientific study done on these things.
As for texture fish have scales and can go at high speeds that underwater mechanical driven machines would love to imitate.
