The logo on Yahoo.com was -- from birth until around 2008 or so -- red. That was the color everybody outside of Yahoo knew. But inside the company everything that could be a color was purple, people were emotionally invested in it, and debate raged on getting Jerry and Filo (who were apparently the holdouts on red) to change the home page logo to purple.

It seems to me very emblematic of Yahoo that they chose their corporate color first entirely at random and then hung on to it forever out of sentimentality. That's the kind of place Yahoo is: fuzzy and loving but not terribly sensible, business-wise.

Changing the logo is a cliché for a struggling company that doesn't have a lot of new ideas. I actually don't think that's true of Marissa Mayer; a whole bunch of her ideas are along the lines of "do whatever Google did", but then Google is very successful, and at least part of what Yahoo needs to do is get better at the things that Google is already good at. But the acquisition-frenzy in mobile seems smarter, and the acquisition of Tumblr smarter still. Time will tell whether it's enough to turn the ship around.

But I still think it's weird that the corporate color is purple.

[1] Chosen essentially at random because they were the cheapest paints available when they painted their first offices. Purple and yellow do not go together at ALL, incidentally.
