Unfortunately, such a color-scheme is not supported (but this is good
suggestion).

But you can do something else that can be useful: you can display atomic
velocities as arrows (vectors). You need to pretend that atomic
velocities are atomic-forces, and then you display forces with xcrysden.
You need to construct the XSF file with "forces" (velocities in your
case). See: http://www.xcrysden.org/doc/XSF.html#__toc__5
