each page a different header/color?

Hello,

Is it possible to easily make a theme or is there one out there that allows you to set the header and/or color scheme for each page? I have someone who wants me to help them do a page and they used this as an example https://www.ashleybeth.com

If there is a theme you know of that already does this, can you let me know what the name is? I’m not even sure what to search for.
