great photos Brian, I love looking at these kitchens in the shire setups

. thank you!
the colors look great, if you haven't tried the following to play with colors, might be worth a shot:
1. I'm assuming you're doing this straight out of the D7000's jpeg's without any post processing, so might be useful to try different in-camera color settings (e.g. vivid, monochrome, portrait, landscape, etc.). The details settings can be changed individually too, such as saturation and hue.
2. Try a long exposure shot with your tripod: it will help you to use lower ISO and decrease general noise and color noise.
3. Can also set custom balance in camera with a cheap gray card, as the mixed lighting indoors will most certainly impact the colors.
if you happen to use Lightroom, the color checker passport is a pretty cheap investment (~70 bucks I think) for getting the colors right* (and some additional adjustments to your taste) by creating custom color profiles for different lighting and subject conditions.
*For the most part, I don't think getting the colors exactly correct is important since: 1. Most people don't have calibrated monitors, 2 this isn't for critical print work, and 3. at the end of the day, it's the perogative of the creator to express the colors however s/he damn pleases

. But the color checker passport gives you good baseline that's quite close to true colors, then from there, you can deviate however you want.
