SharePoint 2010’s Ribbon offers some pre-set styles and mark-up styles for use when editing text. How these styles display is impacted by the Theme which is used. When customizing a theme, be aware of the following relationships:

 

Text/Background Dark 1 = normal text

Text/Background Dark 2 = Mark-up Styles, Headings 1-4 (the default is a dark blue colour of the default top band in SharePoint 2010)

 

Accent 1 = Colour Heading 1

Accent 2 = Colour Heading 2

Accent 3 = Colour Heading 3 and Caption style

Accent 4 = no effect

Accent 5 = Colour Heading 4 and Comment

Accent 6 = Highlight
