Not exactly. Here is how it works: if you specify per-vertex color with your
geometry, Java3D will use that coloring over the colors specified in the
Appearance. Specifically, if lighting is disabled, the per-vertex color will
override the color specified by the ColoringAttributes. If lighting is enabled,
the per-vertex color will override the ambient and diffuse colors in the
Material.
If the effect you are seeing isn't what you expect, you may have found a bug.
As an experiment, try setting your vertex colors to the same color you specify
in your Material. The result should be the same picture as without vertex
colors.
If you continue to see unexpected colors, isolate your problem into a small test
case and send it in as a bug.
