Russell,

Has the the explanation I sent through the Radiance-Support
mailing list not arrived downunder yet? Modifiers just multiply
their values with the material values. And a multiplication based
on blue/green material values of zero will simply give zero again.
You want to use a white base material, and a red logo picture.
