Remap grid RGB

Is it possible to remap the grid RGB in a 3DSMax material? Loading in the grid RGB works properly but I’m having trouble when trying to remap it with Gradient Ramp, Mix, or any map meant to remap the colors to different values.

Any advice is appreciated!
Thanks!

I have found that the standard Output map will function along with the GridTex and allows some RGB curve editing. In the end I’m looking to remap a grid RGB of white/black to red/black and have curve control over how those values are interpreted by the material. I’ll update this when I learn more.
