Indeed. I was familiar with the purple but I went straight red and got 3.14/100. Turns out, the color was changed in June 2008: http://www.thewwwblog.com/yahoo-logo-changes.html

I went "Yahoo!? I don't know, some sort of purple?" And then got 100% on it. I think it's just a really easy color to pick, it's of medium saturation and at the edge of the wheel.

I didn't know either and I went to yahoo and it had an ad on top of the logo. I couldn't believe it.

I couldn't really think of it, but ended up going with yellow.

I was at their campus last week and everything was purple, got an 89.

Ah, I knew it! I was sure it was a slightly pinkish red.
