My formal living/dining room is "Sundried Tomato" on one big wall and the rest of the room is a medium toned green (kinda reminds me of army green). May sound like a bit much but I've gotten a lot of compliments on it, love it, looks so rich! Took a lot of searching for the perfect red, didn't want any pink or purple in it and this is a beautiful red. The entry-way is a lighter color of the green in the living room, love it! Family room/kitchen is neutral light-medium neutral tan/sand color. Gotta be careful with tans, depending on how the light hits it sometimes it looks more toupey and sometimes I see some pinkishness to it (it doesn't look pink but the tone changes). I'm getting ready to pick colors for my master bedroom, I'm doing a rich dark chocolate with pale blue. Haven't figured out for sure how I'm doing the walls but in the process of figuring it out. Haven't painted the upstairs and downstairs bathrooms yet. Downstairs office/bedroom currently light gray w/dark blue accent wall. This will be changed to more neutral tan or toupe color. Kids rooms, will be repainted when they leave home
Good luck with your color choices!
