Today is National Tartan Day. Did you know that Colorado has a state tartan? According to information from the State Archives, the Colorado tartan, or plaid pattern, “is comprised of a pattern and colors that symbolize Colorado’s splendor and history.” The colors of the tartan include forest green, cerulean blue, black, lavender, and white – colors that bring to mind evergreen trees, blue sky, columbines, and snowy peaks. Although it is a Celtic tartan, Colorado’s pattern may be worn by “any resident or friend of Colorado,” even if they are not of Celtic heritage.
