You don't need a regex, a parameter expansion can do that just fine:

#!/bin/bash
string='List of available colors: black blue bluegrey brown cyan deeporange green grey > indigo magenta nordic orange pink red teal violet white yellow'

color=${string#*> }  # Remove everything up to "> ".
echo ${color%% *}    # Remove everything after the first space.
