Change header background color on select pages only

Site URL: https://krill-saffron-kmrs.squarespace.com

Hi all. I'm trying to change the background color of my header on only a few pages. I've tried putting this code into the page header code injection for each page I want to change but it's not working? Any advice?

<style>
	#header {background-color: #000 !important;}
</style>

The pw for my site is: bfe456

Thank you!
