Welcome to Colorado, the state whose “Welcome to Colorful Colorado” sign has a colorful history — even if the sign itself is an unironic brown and white. A garish purple and orange silhouette of those peaks on a metal sign with the slogan: “Welcome to Colorado, mountains and much more.” Flickr/Jimmy Emerson, DVMColorado residents did not welcome the new look, and the original “Colorful Colorado” signs soon returned. One was getting rid of that old ‘Colorful Colorado’ sign from back in the ’50s. Today, CDOT continues to create the “Welcome to Colorful Colorado” signs in its sign shop, with forty of them set up across state entry points.
