Lara, your colors sound gorgeous.
When we were painting our current house, I found it called for a different look than I thought. Our previous house was an 1890s row house, and we used more saturated colors.
When we moved and bought an 1840s farmhouse, I was going to use some of my tried and true shades, but the light quality and general feel of the rooms seemed to need a lighter hand. So we painted in the palest shades of grays and creams. It sounds boring, but with the varied undertones, some rooms look like the palest green-gray, while others are more blue-gray.
FWIW, if anybody is looking for light colors, Benjamin Moore's chart of whites is fantastic. They're not really white at all and give a soft wash of color without overpowering.
