"Why would you want to paint your house all one color?" Because that's what I (and apparently the OP) WANT to do. That's what I like. As an added bonus, it makes it easier, cheaper, and more efficient to get it all painted. Fewer brushes and rollers are needed and you can keep reusing them from one room to the next. Actually I'm going as far as painting in 2 colors. One wall of the great room and the kitchen will be different than the rest of the house. I may do the bathroom in the secondary color as well, that hinges on whether or not that color looks good with the existing tile. If not, I'll stick with the more neutral main color in there as well. I find it more cohesive NOT to paint each room a different color. I had enough trouble settling on the 2 colors I ended up with as it was, LOL!

I have dark expresso cabinet and Santa Cecilia classic countertop and also gold couch. I don't know what color to do for my wall and the accent wall but I really like the light gray like Amazing Gray or Anew Gray by SW. Any suggestion would help! Thanks

You have a little challenge here..having lived in 2 houses a lot like yours for 25 years I am still happy with my yellow...photos never portray color perfectly ....so the advice to try sample swatches ...nice big ones in separate locations..is vital...since color is really a field of it's own you may find some leads for a pro ....color specialist...at your local high-end paint store...I always had the best results having custom paint formulas and know that a home with all those Windows will affect the color at different times of day...another suggestion that will soften the look is to get gorgeous sheers to match your new walls to install at edges of Windows (not really to be closed) and still admit all the light and views
