I would definitely go with the home owner's information. If it is too dark for you, you could try a "half tone" of the color.

Providence Olive was chosen to coordinate with the drapery and is indeed darker than it appears in the photo. (Builder had a professional photographer take the photos so there was quite a bit of artificial light). The ceiling was painted to coordinate by mixing some of the Providence Olive into white, so you might want to ask your paint shop to tone it down to see if that suits you better.
