Hi Murugesh,
There isn't a simple discrete coloring option, but you can do it simply by specifying the same color twice in a palette, once for the low end of its value range and once for the high end of its value range, for example:

color bfactor palette 0,blue:2.9999,blue:3,red:9.9999,red:10,yellow

I hope this helps,

I created an attribute file using z-scores and mapped these scores onto a structure, applying a gradient color scheme. However, I would like to know if there's a way to use discrete colors instead. Specifically, I want to apply a single color with uniform intensity for a selected range of z-scores (e.g., from 3 to 10) rather than using a gradient.
