Another designer is influenced by veins.
A little anatomy clarification real quick – veins ARE blood vessels. They make-up the ‘system’ of blood vessels. Veins just happen to be the ones that take blood to the heart.
Arteries are the opposing spectrum in that they carry blood FROM the heart.
Veins are pretty blue and close to the surface of the skin.
Arteries are bright red and are deeper in the body. They carry that good thing we call oxygen. Here are some images from Julian Zigerli’s line.
