All opposites on the color wheel equal brown. As do the three primary colors, and if one looks closely enough all opposites on the color break down into the three primary colors. Leaning heavier on one or the other shades the brown. And finally, if you are not quite pleased with the shade of brown you got, just tweak it with a tint in the clear coat. That gives the color a bit more depth too.
I realize that his is old news by now.....I've been crazy busy lately and am just taking a minute to try and catch up.
