Color change ?!?!

LucasPD

Hello people,

 

I'm a beginner at Marmoset and I have some doubts. Could you help me, please?

 

I tried to search, but I did not find anything.

 

In this attached image, we have a render and a preview of the image, but we see that the color is different.

 

I would like the same color for the render (brown).

 

What could it be?

 

Thanks for the help everyone.
