One of the favorite colors of the line, named for the color of antique European grain sacks. It's a chameleon color, meaning it looks different depending on what is around it. Sometimes it looks white, sometimes gray, and sometimes more beige.
Grain Sack is a great color to mix with other colors to lighten without making the new color too pastel. It pairs well with the other grays in the line--Shutter Gray and Trophy.
