Believe it or not, there is living room paint progress, though it's going to be slow. Here's why. I decided to paint out the bottom half of the wall to match all the trim and create a sort of wainscoting/paneling effect. This means painting every piece of woodwork in the room to unite the white finishes/colors. And there's lots of woodwork.
The final colors: BM Dove White semigloss and an old Ralph Lauren color called Architectural Cream in eggshell. I can't exactly remember when I got the RL color mixed, but I bought a quart a while back and after lots of testing finally decided on it. I may have cut it down to 75%. Here's the formula if you like it. And I'm not sure if it's exactly readable, so if you want more info, feel free to email me!
The true grays, such as Revere Pewter and Edgecomb Gray didn't work for me, but this light cream does. For the most part. I am still semi on the fence with it—I know, I'm crazy! But it's not too warm, and at times can have a very subtle gray or even green cast. I do like how it changes throughout the day. Now, I have many more hours of painting to look forward to in this room, and maybe a few brush handle callouses, before I can start doing more fun things, like window treatments! Let's hope it goes fast!
