Green Reflections from Terrain/Backdrop

[CJPCsLLC]

Chief Architect X13 user here.  I am experiencing an issue with both the background and terrain colors reflecting on some white surfaces.  From the attached picture you can see the underside of the roof and gutter has this affect.  You can also faintly see it on other surfaces as well. 

 

 

 

I've made plenty of adjustments to sunlight and camera settings without any success.  Providing current screenshots below.  I am looking for assistance on this matter.  Is it the materials I'm using or am I over/under-looking something?  Please advise.

A few suggestions to start:

Save the camera. Lower the exposure to 0.30. Increase sunlight to one of the dropdown options. Increase backdrop intensity to a value between 500 and 5000.

Post the plan.
