Hi there! I’m finding that I’m having some contrast issues with the Waypoint seafoam green for text hyperlinks on the white background/on buttons with white text.
I downloaded Stylebot and made some small tweaks to the CSS on the page to make it a little easier on my eyes. Just sharing them for anyone who may also be feeling a little squinty:
I turned the body’s background color CSS property #f1f1f1 and slightly darkened the Waypoint brand green from #1fd9b7 to #00cca7 on things like buttons and text hyperlinks.
It’s not perfect for me, but it helps immensely. Maybe some much smarter visual designers/colour folks can improve my suggestions 
EDIT: I learned that Discourse has a gorgeous dark theme option, though I still do find the contrast on the buttons of the Waypoint brand colour and the white text to be a bit hard on the eyes.
