Change body text color of a section

[itmakessemse]

Hi, 

On this page: https://adfarm.nl/pages/google-ads i have used some section store sliders. 

I can't change the body text color and i would like to minimalise the widthness of the text. 

How can i adjust it? Normal section functions don't allow me to change it. 

So i want to make the text white and want to change the width of the text.

Thank you in advance.
