The contrast between foreground and background colors do not meet the WCAG 2.0 AA guidelines for all selections.
Default, Arabian Nights and Parchment (sands of dune) do meet AA requirements for all text sizes.
Ballard and Vancouver do not meet AA below 18pt.
How were these colors selected? Was there an explicit choice made for a low contrast theme?
Here is the table of values as of June 18, 2015
