(http://)The light is white but its reflected the color back. If i change it to green the bounce will be green. Is it ok? Found the solution to use rayswitch mtl and put grey material in the reflection slot. But this way i will get all those elements grey in the reflection and thats not what I want. So, is there another solution how to avoid this type of problem? The test scene included

Hi, sorry, but I do not understand your message.
Do you mean that the light reflecting from the wardrobe onto the ceiling is reddish?

I read from the phrasing, that he means the redish color bleed.

Yes this OK and physically correct with strong lights and shorter shutter speeds.
To (physically incorrect) counteract this, you can indeed use rayswitch, BUT NOT the reflection slot has to be overridden with a gray material, it's the Global Illumination Override.
Select thetop Polygons and give it a new face id. Then use multi/sub object material with the ray switch material applied and put in a slighter toned down version of the red texture (put color correction node between diffuse slot and tone saturation down) into the diffuse channel and plug that into a rayswitch global illumination override slot. The rest of the ray switch should contain the original material.
This way you only affect the red color bleed.
If the text is too garbled to read, refer to the video tutorial from the corona YT channel on rayswitch for this issue:
