Bad check for canColor in color.js

[jgarver]

Recently, color.js was introduced to replace the chalk module. It uses a simple check for "process" to determine if the environment can handle color. chalk used the more robust check provided by the supports-color module.

In my browserify world, I have the process module, so I end up with weird ansi color codes in my browser.
