Why doesn’t wolfram.com have a defined background color? Once Wolfram Alpha comes online, perhaps I’ll ask it that question. In the meantime…
background: transparent on the body selector overrides the background color. It should instead be background: #fff
For the record, I do work for a competitor to Wolfram.

Sometimes, the posts just write themselves. There is one thing worse than designers who don’t define their colors: sites that purpose to help you be a web designer, like today’s offender, Web Designer Help.

It always amuses me when designers, who really should know better, end up not defining their background or foreground colors. For example, the two Layer Tennis participants tomorrow both could use some defined colors. Among other things.

Gotta love sites that define background colors on all sorts of items, like links and headers, but forgets to put one on the body.

YouTube’s site used to be correct, but I guess Google’s lack of consistent colors is infecting them. A couple of days ago, their background and text colors were fine. Today, they are undefined.

The Wacom products page needs some adjusting. I always enjoy seeing sites that cater to professionals in the design, art and web development world making these mistakes.

Boing Boing: Offworld is just a tad difficult to read, since they’ve neglected to define their text color.

Reddit.com’s comment system is hard to read, since they omitted to define their text color. I also picked an amusing example: "If you’re a web designer working alongside print designers with little to no web design/dev knowledge, how is your experience?" My experience is that web designers should know enough to define their text colors.

I love Geeks of Doom, but they really need to define their colors.
