Ask HN: What do you think of HN Christmas 2011 theme?
My first comment would be about black colored links are not readable on maroon backgrounds.
(Though as I was posting this, I briefly got all Marooned, then it went back to standard orange.)
If it's really necessary to do something for Christmas why not just a small tree next to the logo, or perhaps replacing it. Changing the color scheme to me doesn't really add much Christmas flair to anything, it just makes the familiar design more jarring.
The color simplicity is one of the best things of HN's design.
It's OK.
