2 Good color tips: 1. I love themes. Pick a theme for a room, such as a collection or object, and follow it for color and furnishing choices. 2. Don't rule out colors. I hate purple, but my dining room was the loveliest silvery lavender when I moved in, and it really is perfect.
Favorite type and brand of paint: I tried Benjamin Moore Aura for my bathroom, and I was happy about not breathing excess fumes.
