Camouflage is an interesting concept in itself because it is born out of a union between art and science. My curiosity with concealment techniques and technologies has been peaked since spending time in Africa where the multitude of species and the simple-complexity of their individual concealment is mind blowing. The Swedish armed forces use M90, "this pattern employs hard lines of geometric shapes in order to create a camouflage pattern effective in the temperate forests and plains of Sweden. M90 camouflage comprises four colours: dark green, medium green, and dark navy blue on a light beige-coloured background." I'm tempted to M90 the Super- Duty one of these days.
