> But I wonder if it has anything—even in small part—to do with the bad contrast on a lot of sites and the fact that browsers render highlighted text with good contrast. Even on high-contrast sites like Medium, the bright background combined with dark text can be tiresome on the eye, meaning that highlighted text will invert that yielding a more comfortable white text on blue. As someone who doesn't randomly highlight text, I often intentionally highlight text to quickly and nearly-effortlessly correct bad color selections by the site's designers. Mostly to ensure I keep my APM high on HackerNews.
