Window looks in different color

[eneskaraca]

I created a window style, to create new window I copy the window parameters from previous with alt click and insert the new wall. But here is the thing it changed the color. I move side by side the two window as you can see the original one (upper) is darker color but other has lighter black color. I checked all the color settings but they are same. I couldnt figure out can you help about that?

Operating system used: Windows
