Chromo is an unincorporated community and U.S. Post Office in Archuleta County, Colorado, United States.

In 1922 the Chromo School was built to serve the children in the area and operated from 1922 to 1954.

The original school building, a concrete structure, now functions as a community center.

The well-preserved building is an example of a rural school complex, containing a teacherage and an outhouse.

This climatic region is typified by large seasonal temperature differences, with warm to hot (and often humid) summers and cold (sometimes severely cold) winters.
