All of my hats are made from the fine and soft wool of purebred Cormo sheep.
The hat colors are the actual colors of the fleeces of the sheep (white, black, and gray), and blends of those colors.
White Cormo fleeces are a bright white, not a cream color.
Black and gray fleeces become brown-tipped after exposure to the sun; so the more dark wool in a blend, the more brown the color.
My light grays are warm grays; my medium grays are brownish grays; my dark grays are very brownish grays; my darkest shade is chocolate brown.
