For a style Heading 1, I see this: Font: (Default +Headings (Calibri), 11 pt, Font Color: Background 1, All caps, Indent :left 10px, right: 10px Space

for other Headings like 2, 3, 4 the Font Color is Accent 2 (or three)


I would like to be able to change the background color for styles to be different than the page color. How do I change and modify the
Font Color: Background 1
Font Color: Accent color

What you are seeing is the labeling of Theme colors.
Background 1 is simply a color. On my machine, in the current theme, it is white. If you chose that for your color you would have a white font, not necessarily a white background.

You can have a background (called shading) if you want.
When you modify the style, click on the Format button and choose shading.

Understanding Styles in Microsoft Word

I have been using word 2007, since 2007. I was unaware of themes. Thanks for taking the time to post and for the most excellent link. I need to update my knowledge of themes, style sets? and how to use CSS formatting for word docs.

this link helped go deeper on understanding what I was seeing.

I don't know themes. As for CSS, see:
