Change color a page

The page it's a contact form with contact form 7 plugin, I've installed contact form 7 Customizer, and I can change the color of the diferents box in the frontend--- Personalize---CSS Customizer
But not the background page

Hi there,

Any chance you can link us to the site in question?

You can edit the original topic and use the private URL field.

Let me know :)

I have sent it to:
https://generatepress.com/contact/

Is there a specific page I should be looking at?

And what CSS have you tried?

1º The page it's Libro de Visitas.
2º I have erased the whole CSS because none was working

Which color are you trying to change?

The white background color for the content?

It gives me the same thing, the color that is already I will change it then if I want for other one.
Now the color box of the Contact Form it's #f46464 and I will change the container of this page only (that it's white now) to the same color of the Contact Form like #f46464, not background color page that it's #bea0c1.

Ohhhhh
Already I could have found it, with Tom's code
.separate-containers .inside-article {
background-color: #FFFFFF;
}
It's workslike a charm
;)
Thank you and estimated by your patience

Yup that would be the correct code.

No problem :)
