I have just noticed that the colors of the numbers for posts now alternate between red and green. And the header graphic background color is now ox blood red. Is it site wide or is it just me?
The darker red is a lot more pleasing to the eye, at least IMO. It has a nice contrast with the orange 'Y' logo.
However, the 'Hacker News new | threads ...' text really needs to be white for this new background, black doesn't have enough contrast. As a bonus, white text here will jive with the white Y better.
Seriously, I clicked on an internal link and freaked out a bit. I could not remember whether the previous page was similarly colored (and I just did not notice), or whether the change just happened.
I know it's a bit of a dead horse now but one could say that the User Experience has changed because the colors have changed, but the User Interface has not changed.
