Hi Nekrobul,
thanks for your reply.
The reason why I asked is because even using a material with just 0.5 Reflection I still get a pinkish color (see the attachment). But I was having a hard time trying to remove the burnt white area and now by removing some reflection and changing the colour I managed to have a better result.
For now, I am trying to get a more interesting composition with this render. I may have to change the camera angle. Any suggestions?
