There really is no substitution for testing the colors in your space and different light through the day. For a suppposedly neutral color, greys can be tricky. Fact of the matetr is that a greyy can be any color plus black or some canceling tones. Revere Pewter goes violet on me and Edgecomb grey a bit green in some rooms. I wound up going to Sherwin Williams and trying their colors. Agreeable Grey was the right tone for my living areas, but I am doing them at 150% to get a little deeper color. I am using Anew Grey in my entry and stairwell -- that hasn't been done yet. . More important to your question about going with cool and warm colors -- the Agreeable Grey in my FR had to work with red brick, cherry hutch and dark wood floors as well as blue, green and white in the upoho;stery, rug and kitchen cabinets and counters. Anything that tended green made the red brick fireplace more intense and anything too warm made it pinker/orangier. Agreeable Grey at 100% was too light -- was too close to my grout and looked chalky, so we just added more color and went to 150%. SInce it is a light color to begin with, it is still light, just richer. The result was amazing -- my red brick calmed down. No more orangey, purpley/brown red. And it is so soft and neutral with the blues,, green and white. We did the ceiling at a reduced value. It was the first time I had used SW paints and as much as I liked BM, I was just as pleased with this job (DIY).

Not sure what family of colors you're into for trim (blues, greens, etc) but I've been looking at Homburg Gray (Sherwin Williams) for updating my shutters & exterior doors. I bought a sample planning for a bedroom and though it didn't work there I know I'll find some way I'll incorporate this gorgeous deep deep bluish green into my home color sceme.

thank you, Cara. unfortunately white door is not an option. I like the wood grain to show. I just realized that it is not easy to pick and match color online. but I got some stain, dark mahogany and walnut. I will strip and stain one door to test. thanks for walls gray color though.

We found that the Shitake really changed tone depending upon what it was surrounded by. I would suggest painting a large sample board and moving from place to place in your light and against your other materials. I found choosing paint colors the hardest part of building our home. You have to have a large sample and take to the actual place you want to paint it to see the light because it changes depending on where you are.
