Title Background Text Colour

Hi There,

I’m currently having a bit of trouble and have been up all night trying to solve this problem to no avial.

I wanted to see if anybody knew how to add a background text colour to the titles of my blog posts, I have an example of how they have done it here http://wplift.com/how-add-text-featured-images-different-scenarios

This is a link to my blog http://www.66till.com , is there anybody who has knowledge in this?

Thanks
