Battery 100% charged, icon showing red?

So, the strangest thing happened. This morning I used my new MacBook Pro (only had it for just over a week) down to about 28% and decided to charge it for a few hours.

Just now when I opened it up (the light on the cord was green, indicating full charge), the percentage showed 100% but the battery icon was completely red!

It "corrected" itself when I changed the display options to Show -> Icon Only and then switched it back, but since this is a new computer and I didn't find anything when I Googled about it, I just wanted to see if anyone else has heard about anything like this.

I took a screenshot:

I just created an account to comment here. I just had the same thing happen to me this morning. Upon opening the laptop, the battery icon was red, and had 100% charge level.

I calibrate my battery nearly daily.
