Answer for How do I change the main Text colours?

Hey Kevin, how are you?
 
Sorry for the late response – been very busy in the office.
Quick question, could you link me to a live demo of what you showed me here: http://jsfiddle.net/ycx5oy4j/. 
If you can find a website which uses that script, my friend will be able to see practically what it does, so he has confidence in moving forward with the $100 customisation. 
 
Cheers,
Josh
