I highly recommend using Full Spectrum Paints. The cost of materials is relatively minor compared to the cost of labor when painting. Invest in the best that you can.
Full spectrum paints are offered locally by C2 and Benjamin Moore, Color Stories.
Full spectrum paints utilize many more pigments than typical to create their color lines. Each color is comprised of 5 to 7 pigments, not the standard few used in the industry and they are never made with black or grey tints. This use of so many pigments in each color formula as opposed to the use of black or grey in the mix makes full spectrum paints complex colors of great depth and luminosity. They appear mutable as the light of the day changes and because they contain so many pigments they make stunning color combinations in and between rooms. These paints are all low VOC.
Farrow & Ball, Benjamin Moore, Sherwin- Williams and C2 all offer color ranges of great depth and beauty.
