Is Black a Color?

Okay, now I'm just trying to start a fight in the comments.

This seems to be a topic that most people have strong opinions on, despite its being a relatively harmless one. It goes without saying that there are two main arguments:

1. Black does not exist on the visible light spectrum. Therefore, it is not a color.

2. Black can definitely be listed as someone's favorite 'color.' We use it with all of the other colors. Therefore, it is a color.

And that's pretty much all there is to say about that. It would be great to see all of the different interpretations, but it's interesting that people's opinions are so polarized on this one topic.

On a very, very slightly related note, I really enjoy the use of black as an adjective to imply shade. I mean, there's one mineral that's supposed to be the 'blackest' thing we can experience. Did black get promoted to a feeling? Or are colors too closely tied to our feelings for us to differentiate between both?

Oops. I gave away my stance.
