Why has the HN theme changed?

It's a Christmas theme. I think they leave it up only 24 hours? I'm not sure.

You can change your top bar color. Mine is not the standard, so I forgot they did something to the top bar. I only have the alternating colored numbers.

This seems to be a bigger problem than just HN. Several of my neighbors put distracting lights on their houses without considering color theory. I noticed some green and red decorations at the grocery store too, clashing with the usual white/blue theme.

I had planned to spend Friday catching up on HN but after two minutes with these colors my eyes starting watering. Who decides to make these arbitrary changes?

I'm developing a hypothesis (which I will eventually describe in a Medium post) that these color changes and attempts at decoration coincide with certain days of the year, but I haven't quite worked out the pattern yet.

I require an explanation for the these red and green colors showing up on the 25th of December!

Merry Christmas HN. :)

The contrast is too small in the navigation bar now, very hard to read the black on dark red unless I turn the brightness up very high. And the coloring of the numbers doesn't really do much good either, I agree.

To piss off color blind people! :P
