I copy my snakeskin off of a Deano's bike that I saw a couple of years back. It has 4 colors, plus black. The snakeskin was to be done in a diamondback-color scheme. These are the colors I use: medium brown, a light brown, a medium green, and a medium red. All of these colors are 'earth-tone-ish' colors..nothing bright, and flat, opaque colors, nothing translucent or metallic/pearly.
I start off, spraying the entire background the medium brown. Then I come back with the light brown, and spray a 'diamond' shape line, in about 3" by 3" squares, about a 1/2" wide line. So now I have a light brown cross-hatch on a medium brown backtground. Then I come in and I spray all of the center 'diamonds' the medium red, and I fog some of the red on the inside edges of the outer diamonds. On real snakeskin, the red color is on the areas of the skin facing upwards, and so the side diamonds have a little red on them. Then I spray the medium green on the outside diamonds.
Then after everything is done, I use the 'loufa' trick. I take apart an un-used loufa (the thing your wife uses to bathe with), and stretch it over the snakeskin area...tugging and moving it around to where I need it. Then I take all four colors and darken them about 20% and re-spray the entire thing. I know this sounds confusing, but I'll try to get some pics up tomorow..you'll see what I mean. It makes EXTREMELY lifelike snakeskin.
