Link colors in upfront

Please refer to the attached Image. I need to set the global colors for links to be unique to a region of content. For instance as you can see in the picture I change the color for links in the global settings to a light color for contrast in a dark bg but not all regions are dark. I would like to set them up so that each region has a color schema for headers and links and such. How can I achieve that? Templates?
I need a set and forget format for the default page, the default blog post list page and the single post page so that contributors do not have a need to fool with it and I don't have to go back in a change it whenever someone updates the site.

Thanks for all the support you provide here.
