Colton is a trendy two-syllable choice, with the popular 'on/en' ending.
Colton jumped onto the popularity list in 1982 at Number 806. Then, in 1988, the hunky character Colton Shore was introduced on the soap opera General Hospital, and the name began to zoom up the list, till it has now reached Number 68. Coincidence or contributing factor?
Another attractive namesake is Teen Wolf heartthrob Colton Haynes. Short form Colt has been used by a couple of celebs.
