Colorize cluster inputs per c#

Hello, is it possible to color the inputs in a cluster with a c# node to help the user determine which inputs are fixed (inputs from other nodes) and which are their own inputs (e.g. to change the offset and so on)?

I’m trying to find a way to make the clusters more user-friendly, especially when people with no or minimal Grasshopper experience use the scripts.

Maybe someone has an idea how to implement it.
