Is there a way to access the overwritten per object materials in a renderer?

I have set a bunch of colors through the MaterialBlockProperty functionality, now my next part of my code wants to access the material colors of these objects, but that is just black because it hasn't been changed, the renderer has overwritten it on each object to color them, how do I access the overwritten properties of a renderer? there is a propertyBlock.getColor function, but there is no way to get the propertyblock in question from the Renderer?

Any help would be greatly appreciated.

Cheers

 

You set the color via

renderer.SetPropertyBlock(matBlock)

, there's a matching

renderer.GetPropertyBlock(matBlock)

you can (and should!) use to access the block that was set.
