I am trying to match a vortex razor as well.
I looked at a bunch of swatches, and the patriot brown is almost exactly the same color as my razor, but it is flat and doesn't match the shine the anodize has. The burnt bronze matches the sheen of the anodize but it is lighter and not as dark brown.
I will look at the tungsten grey again, but my razor must be very brown, because patriot brown was the closest match and tungsten grey was not close at all.
Is there a way to add flake to the patriot brown?
