jmason and I come from the same neck of the woods but appear to have completely different "taste" in rifle colors.
Rifles are "painted" apparently to be pleasing to the human eye. To fit man's imagination or look cool rather than hide from the enemy (chucks, PDs, deer, elk, moose etc, which are all color blind anyway).
For the rifle, if you set it down to 'find a bush' you should have to hunt for it when you're done.
This experience usually occurs only once as one quickly comes up with a fix such as a bread crumb trail or a tether.
The colors/shades should match the ecosystem in which the rifle will be used. This certainly is an advantage when the game of interest is a half mile away across a canyon.
Also this concept makes it necessary to have a different scheme for each ecosystem. Makes things easier to explain to the wife when a new rifle show appears on the scene.
Google on reticulated giraffe and use that pattern. Pretty cool if its duplicated properly.
I'm in the final stages of refinishing my red/white/blue LRH rifle. It looked nifty on the range and drew comments from hunters moving by the shooting spot but didn't fit in the sage brush when ambushing yotes.
Speckle the squat out of things. To ensure random spots or texture use the tried and true tooth brush technique (outdoors, not the wife's kitchen).
