How to change defuse colour in unity Euclidoen SDK

I am using Unity Euclidon SDK and it i found it is working with a Custom post effect. My question is that is there any way available to change the default diffuse colour? Albedo colour in unity? I mean the current model redering is quite bright i want to less it want to make more grey? Is this possible cause i am not seeing any material here? I am using  basic render scene.
