I wondered this the other day while working on a website. On the top of the site there is a header with three words, each a different color. The third word is blue. It looked fine during the day but at night, with flux turned on, I was unable to see the blue text against the black background. I actually made the decision to paint the header the same color as the body text. No idea how many people will view the site with flux on but since _I_ need to look at it a lot, I figured it was a good change to make.
