Different content background colors on frontpage and rest of site?

Hi,

I’ve been tinkering with the theme and I end up faced with a dilemma I’m hoping someone can help me with.

I would like the columns on my frontpage to have a background color (#C7C7C8) which I get if I assign that color to content in Parabola Settings/Colors. But if I do that, then all the rest of the content like the blog posts, pages, etc. have that background color which I don’t want. I would like them to remain white.

As such, I think it would be simpler to just leave Content background color as white and simply use custom css to change the background color for those columns. I tried so many combos looking at the source code to see which id and classes seem to regulate the look of those sections but I haven’t gotten anything to work the way the theme does if you change the content color.

#front-columns just assigns a kind of border around my columns so it’s definitely not that one.
#column1 (and subsequently column2 and column3) does nothing at all, and neither does using .ppcolumn column1 (and others)
I also tried using #column1 .ppcolumn column1 and various other combos to no effect. Everything remains desperately white.

Can anyone assist me?

Thank you for your time and help.
