customization color surface analysis (civil3d)

[Ackab]

Good morning
I need to know if there is a lisp or tools to set the colors of the analysis surface based on datum different from red, green, rainbow soil..... my personalization.
I did the thing by hand on a specific surface and level curves within a surface style.

Thank you.

Hey, can you be more precise?
do you mean to customize the colors that gives you the surface analysis style of civil3d?
you have an example file (to understand), even a flat surface/tilting plane
