Why is my memory in iTunes discolored?

[Cjr605]

If you plug in your iPhone, iPod, etc. you always can look at the bottom of the screen to see how much memory you have, and it is conveniently placed on a "timeline" (or whatever). When I look at mine, in the music section part of it is a darker shade of blue than the rest.

Why??

I believe the darker blue indicates music videos, whereas the royal blue indicates MP3s.

Or are they iTunes Plus songs?

Agreed, after looking further into it, I found they are music videos..

Wouldn't it make more sense to make it a different shade of purple? Just a thought
