Hi Michael,
It wasnt that. It was I was setting the first object to "Default" and the script turns that black.

So default to black "looks" like all objects are black

I set a new style of "Very Light Black" to Black, and the gradient appeared. If i set First to default and something like Blue, I get Black to Blue...

Anyway, figured out how to use it pproperly. Has something to do with the default color and the "Black, not really Black" Shading vs Lines thing.......
