Weird. It's #000 on #FFF, unless my meager CSS skills have failed me. Maybe it's just too thin or something? I'll see what I can do but probably not today. /points to the markdown link in sibling comment.
The 'Lato' font is unreadably thin for me on Linux. If I turn it off (via inspect element) and allow it to use the next one (Helvetica) then it looks fine.
Actually the company firewall here blocked it because it automatically recognized the hexy domain name as 'suspicious'. Which if you think about it is kind of smart...
Worth knowing too - people sometimes hide analytically servers off on cryptically named domains, and maybe they get eaten by firewalls more than you'd think.
