Colors.js: Proper syntax for adding a color to a variable (string)?

Question

In addition to my static message (which displays just fine), how would I make the variable named 'port' green in this console.log?

console.log('Express app started on port '.green + port);

I don't see anything about adding colors to variables in the docs, and of course if I just add .green to port, it will look for the .green element of the port var which will be undefined.

colors.js modifies the string object -- try

port.toString().green
