Center align two or more columns

Hi guys,

All the way at the bottom of my site there is a color section with four columns. Column 2 contains a picture of people walking. Column 3 contains the heading ‘Over Emanon’ and more text. My problem is that 1/4 columns are to small. And 1/2 is to wide.

So I want to make the whole a little bit wider by making two 1/3 columns and then center them.

I followed the steps in the Enfold Documentation: https://kriesi.at/documentation/enfold/columns but it’s not working.
All the way at the bottom is the color section I used trying to center it. Can you help me out?

Thanks in advance. And keep up the good work. This theme truly is amazing. Lots of possibilities and so easy to use.

Greetings
