Black Backface Color

Hi,
is there a way to change the color of the backface of polygons? Actually if i make more darker material and have some backfaces for example on one side cloth objects, so they are completely black. see screenshot

thanks in advance

Edit > Preference > Colors > Object Colors > Back Face Color.

Ahh ok thanks a lot for info!

I get it now why they where black. The color was set to red in options,
but i had to check,

View>>Object Shading>> Back Face In Grey , so i can see the color.
