This was a serious question. My vision is not what it was when I was younger. I am finding more and more websites are very difficult for me to read, and this one was unreadable for me without the help of Evernote's Clearly extension.
I am a firm believer in the utility of web frameworks, and I'm always willing to look at new ones. I assumed that the tutorial website had been built using Ember.js, and my first impression was not favorable.
You may need to adjust your monitor settings or buy a new monitor. The difference between #232323 and #FBFAF7 should be enough contrast. The Trek logo is even higher contrast as #FFF and #171717.
I believe trek has updated the site's theme in the interim. I was also having some contrast and font size issues, and the new theme definitely addresses my complaints.
