How to change colors of loop tool (currently grey)

[kleemax]

Is there a way to change the 4th color of the loop tool? Currently the 4th color is grey. Taht is problematic if the arrows are already black and then when dimmed out appear grey also. I use PLEPlus. Hence I wonder if Pro has the possibility to customize the colors used by the loop tool.

It's the graph plot colours that are used (under Tools->Options->Graphs).

I'll create a ticket to allow customization in the future.
