We have not so good contrast ratio. Using e.g. Lighthouse, we have these results

P.S.

This extension (from Google) adds an option to audits section in dev tools to verify a11y rules. It procies hinted color that should be used instead of one failing tests based on luminosity change. So you could do adjustment pretty mach based on this tool hints:

The footer is secondary content (always hidden under the fold), so this should be OK to just fix color using hints (for links)
The masthead buttons background color is the other thing. Just check what you get with a11y tool

I think we should just ask @samccone to tweak lighthouse so marionettejs.com passes. 🥇
