sifr color selctor changes

Question

Ok, so I am using h1 selector. On one web page I need the color to be orange on another web page I need green. Each item is using the h1 selector. First, I am confused as to which file - sifr-config.js or sifr.css to update. I think it's the config file but I am not sure. Anyway, in my config file I have the following:

sIFR.replace(vipernora, { selector: 'h1,h2', css: '.sIFR-root {color: #eb4615;} .green{color: #008000;}', wmode: 'opaque' });

For the h1 selector I need green, I created a green class and in the selector html I added
class="green" to the particular h1 tag

But it doesn't appear to be working. To make a long story short, how do you do this?
