"ref_color1" default changed on me

[tsorel]

The default gray part color has changed on me to a bright white. I cannot find any way to change it back as all the sliders under "ref_color1" are not active. I typically use a white background so now my new and existing parts and assemblies are bright white and not very visible. I think what is different is the "intensity" and "ambient" which are now both "90" whereas I believe they were around 50 or 55 before. I am on Creo 3.0, M010
