How to change panel colors

Hi there

How can I change the panel colors as per the attached image?

Also, what is the font in the paragraph text?

Hey there

I hope you are well today and thank you for your question.

  1. The font being uses is Raleway

You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.
Admin Area -> Appearance -> Customize -> Additional CSS

/*change section color*/
#shapely_home_parallax-10 > section {
    background-color: gray;

Best Regards,
