We used Promaster 2000 eggshell to paint an entire one bedroom apartment in St. Louis' trendy west-end.  The coverage was great!  The customer had selected Behr Gobi Desert (710C-3).  The color was very neutral and we would suggest you consider this color for the main areas of your living space.

Porter's High Hide Ceiling White is an excellent choice for your ceilings.  We add 1 drop of black and 1 drop of umber to each gallon of paint as we fell this addition improves the paint coverage.

Other new colors we like are Adobe White (513-2), Bread Basket (317-6), Bahia Grass (310-4),Bamboo (312-2), Woolen Vest  (412-4), Battan Palm (512-6),Tabu (412-3), Brandied Pears (315-2), Golden Ecru (316-4), Almond Brittle (316-3), Applesauce Cake (316-5), Creamy White (512-2), Almond Cream (315-3), and Rum Runner (232-7).

Another color we like for a neutral is Porter's Antique Frost.  It is not in the current paint fan deck but is still available.  We just did a two story home in St. Charles in this nice color in eggshell.
