  The W3C recommendation you referenced has an online tool to check specific colors: http://juicystudio.com/services/luminositycontrastratio.php#specify
  
  Current breeze colors give
  
  > Passed at Level AAA: The luminosity contrast ratio is very good for the chosen colours (#fcfcfc and #31363b).
  
  There are also studies that warn against using too high contrast in text. For example https://www.researchgate.net/profile/Ricardo_Baeza-Yates/publication/239761586_Layout_guidelines_for_web_text_and_a_web_service_to_improve_accessibility_for_dyslexics/links/02e7e53313bbc5c9bc000000.pdf
