Having read partway into Chapter 2 of The Elements of Typographic Style, I have come to realize how difficult to read a long line can be. With the magic of sizing the font based on screen width, and larger margins, lines are now generally 65 to 70 characters in length, regardless of display width.
A teensy weensy bit of a third color felt like it could do well to act as a sort of accent, and so the underlines of links are now turqoise.
