Color change only effects surface edges

Test HD.3dm (3.8 MB)
I’m having trouble changing the color of a surface.The only unique thing about this surface is that it was previously part of a block. When I attempted to change the color of the surface it only seems to affect the edges while the surface ‘fill’ remains unchanged. I’ve tried changing the color in model space, layouts and by applying a new material but nothing seems to work. Attached is one of the surfaces I’m having trouble with.

Hi Haines use RemovePerFaceColors for this. My guess is it came in as a step file, maybe?

That worked, thanks!
