Change Exterior Walls Color/Texture

[RohitChandra 0]

I would like to change the color of all exterior walls (so as to experiment with different paint colors), how can I do this? 

If possible I'd like to change the texture also from siding to stucco.

 

I'm using Home Designer Suite 2017 (Build 18.3.2.2x64)

Click on Materials>Colors            for the textures click Siding and Paneling.
