How to change a PAGE background colour? Seems to be automatically white?

[SMorgan1]

How can I change my PAGE background colour in Shopify? 
I've linked my Privacy Policy page to the correct link, but for whatever reason cannot edit the theme within that shopify page, so the background is white, when I'd like it to match the rest of my website with colour #F8F5F0 with #33271D as the font colour.  
Any suggestions?  I've tried editing the code but that hasn't seemed to work.

Hi AnneLuo, 
I managed to fix it by updating the Custom CSS on the page.  Thank you for offering your help though! 

For anyone else needing assistance with this - the easiest way is to go into customise your theme, navigate to the page you'd like to change the colour of, and from there edit the 'Custom CSS' for that page.  

Simply add the below: 
{
background-color: ENTER COLOUR YOU WOULD LIKE;
}
{
font-color: #ENTER COLOUR YOU WOULD LIKE;
}
{
title-color: #ENTER COLOUR YOU WOULD LIKE;
}
