Vray lighning issue

[Riyona]

I have set the camera and it always appears blue , i wounder why it happens and instead i wand the walls to render white but not blue

The blue color is likely coming from your light bouncing off of a blue object.  I know there are ways of reducing this effect (referred to as "color bleed") but none come to mind right now.  A Google search should help out, though.  It will depend on what renderer you are using and what material type is using the blue color.
