Wall Colors

Use KM3852-2 "Constance" in the formal living room. It will be gorgeous! Sophisticated and elegant. The contrast with the white couches will look crisp, and this color will bring out the soft blues and greens in the area rug.
AC217-R "Terra Rosa" is for your formal dining room walls, and use KM3993-1 "Cloud of Cream" for the ceiling in this room. This rich but soft red will give an elegant and striking look for formal dinners and holiday celebrations. With dark furniture, crisp white linens, candles, and some cream-and-red striped window treatments, it will be the star of the house.
Use KM3948-2 "Meadow Brook" for the walls in the big basement room. A stronger color in there would be too inflexible. This is a good neutral that will warm up the space a little, and harmonize with the carpet. Let the toys and futons bring color into the space in this room.
Here's your bold orange! KM3640-5 "Persimmon" will look delicious and is a nice modern touch to the clean, traditional sink and cabinet. In this bathroom, use 3"x6" porcelain subway tiles in white with Laticrete grout color #44 or plain white. The floor should be 1" hex tiles in white with Laticrete grout color #34.
