With only 2 colors spray the Majority of the frame with the darker color in pretty good sized sections but not the entire stand. Go about 1/2 and 1/2 with the factory stand color.
Then break off a branch with some interesting leaves or some thick blades of grass to use as a stencil. Spray the stencil against the frame with the light color letting it fade out to the edges to give the effect of some depth and when you remove the stencil you'll have the "leaves" show up as the darker pattern against a lighter background.

Just mess around with it........you really can't screw up camo'ing a stand.
