In Scotland, different patterned tartans, or plaids, are used to symbolize different clans, or families. Well, did you know that Colorado has its very own tartan design? The General Assembly adopted the state tartan in 1997. The dominant color is cerulean blue, accented with forest green, black, lavendar, gold, white, and red, all chosen to symbolize something about Colorado. The Colorado statutes declare Colorado Tartan Day officially as July 1, but Colorado legislators wear the state tartan-patterned ties and scarves on April 6, which is National Tartan Day, since the Legislature does not meet in July.
