thinking about using the trusty tan as a wallcolor instead of the spalding gray. i like these two colors! use trusty tan and the Waterscape on an accent wall? from "How to paint your home to look like a spa" and some color choices to get you there.
Match to futuristic/space Traveller ooh. this would be a super fun project. color-match spectrum of a favorite photo. even more so if the spectrum was also collaged from photos, not just color matched on illustrator.
