I didn't look into how you're doing this, but crayon(n)('some string') is massively slow.

Essentially all you need to do is "\x1b[38;5;" + n + "m" + "some string" .. so some perf is in order.

Swapping out your lib for a simple custom function that did that resulted in what looked like a 100x boost.

from your README:

// Set just the background
console.log(chalk(null, "gray")("this will be the default text color on gray"));

That code blows up.
Error: Don't understand the color 'null'
