Ok these all go into the same sub (page_props) so you need to merge them.
Also noting that if these are all background colors it's best to say so in the property name. It makes it easier down the line to know what's what if there are fixes to be done or new features do be added. I would also make the description shorter "Content headers background color" and move the note about transparency into a proper note:
property Color color_content_header_background { des = "Content headers background color"; note = "Leave blank for transparency." }
no subject

Same things for images. You can see how properties are conventionally named and described if you look at Core2 (http://www.dreamwidth.org/customize/advanced/layersource?id=550&fmt=html). This is is in the 'Journal style - images' and 'Journal style - element colors' sections.
