changing color of symbology on mfd (F18)

[bloomstombs]

Hi, anyone know how to change the color of symbology on the right mfd of the f18 mod ? 
Specifically im looking to change the colors of the red symbol enemy contacts (from datalink). Impossible to read in VR .

I tried editting the colors in materials.lua from red to orange but it did nothing from I can tell. Also messed around with the controller file in radar_aa.lua just to see if I could override it, and again nothing.

Thank you , would very much appreciate it!

I am in materials.lua and it says specifically that red and yellow will be set via dedicated controllers.. Does this mean those controllers are elsewhere or are they simply hardcoded into dcs and cant be changed?

This would help the vr community a great deal if we could get rid of these red saturated symbols to something more readable.

Thanks in advance for any input.
