VRayLinkedMtl Problem

[The Graduate]

Hi this is my first post here although Ive been using SU for about 4 years, Im new to VRay.

My problem is ..

Ive created a new VRayLinkedMtl, Its a simple vibrat red ceramic wall tile for a bathroom. I have resized the material and positioned with no problem in SU. However when I update the view in VRay's Material editor the colour changes to a 'washed out' dull red/pink. Ive tried all sorts to get the deep red tile I want in my render with no joy. any help or ideas would be appreciated

Thanks a lot
Steve
