Color Difference between final render and material override

[Wincowski]

I have an urgent issue with color of the element. In frame buffer with material override my walls color looks like normal as I want, I except the wall from clay material, but in normal mod with all textures the walls look like darker. I didint change any material setting between this two mod

Since Corona simulates real life rules of light transport, there are these things called "reflections" and "global illumination" in it. If you render a dark wall surrounded by dark objects, it will look different than the same dark wall surrounded by bright objects.
