Why don't colors match from Library Browser to Camera View?

Hi All,

I chose white vinyl siding for the exterior cladding...however…..it shows dark gray.

I don't think it is my monitor…..as I looked at a number of the designs posted in "show & tell" thread (very impressive, BTW) and I can see white in those designs.

In addition, although I chose white for all of the window frame elements, the cladding for the windows shows gray as well...a tad lighter than the siding...but most definitely a dark medium gray What am I doing wrong?

TIA
