Kristine, you need multiple pigments in the formula. Whenever you have a color like Waterbury Cream that contains a yellow colorant, like yellow oxide, and black which is used to tone it down, it create within the color a dimension of a green cast. The aspect of green is always there because it's intrinsic to the paint color due to the mix of colorants. Whether the green cast shows in a room or not depends entirely on the quality of light. There has to be a similar aspect of green within the light source to "catch" the green cast in the paint color and reflect it back into the room so you can see it. One of your rooms doesn't have that quality of green within the light, the other one does. It's that simple. You have a quality of light that goes from one extreme to the other. We know that because you noticed that every warm color looks dirty in the morning and on fire in the afternoon. So the answer is a paint color that can go from one extreme to the other too. One that is mixed full spectrum, like Ellen Kennon Full Spectrum Paints or multi-pigmented like from C2 Paints.

I'm not 100% sure it's hardy in your zone, but Lithodora is a perennial with white, blue, or white/blue flowers depending on which variety you get. The varieties "Grace Ward" and "Heavenly Blue" have a flower color that is similar to the "lobelia blue" you mention. In my area, it usually has a big flush of flowers in mid-spring, and then flowers on and off through the summer. It has dark green foliage, spreads slowly, and is able to shade out a lot of weeds. It requires very little maintenance, which seems to be what you're looking for. Also, as far as blues, there are a number of Delphiniums that have very blue blues, but keep in mind that the entire plant is poisonous to pets (and humans). These require a bit more maintenance and don't have perennial foliage. Having a basic color scheme is also helpful when selecting plants. Silver does a good job setting off blues. Examples are things like Dusty Miller or Lambs Ear. Yellows go well with blue. An occasional bright pink or red (e.g., from the Dahlietta series of Dahilas) can provide some pops of color against a green/silver/blue backdrop.

Hello Renee, what color is the rest of your house? do you have any preference? what is you/your house style? what color is the furniture/floor/walls on the adjacent room? Of course shades of white are usually a safe way to go, but am guessing you are looking for something other than white.
