Want more flexibility with accent colors to avoid contrast issues

As I chew on this more, the automatic text contrast changes like that are on some of the newer theme elements are fantastic, especially for elements like Continue buttons. Expanding it to all elements is a huge step forward. 

However, there are cases when a color picker would be preferred so that the color is something other than the accent or black/gray and still fits in a style guide. For example, setting hyperlinks to be blue is our preference over our gold accent (low contrast) or black/gray (identical to the surrounding text). In this example, a global course setting to set a hyperlink color would be ideal.
