Changing Google Notification Colors

[Whitechapel]

I was wondering if there was a way to alert how Google notifies me, specifically the LED colors. I have 2 separate email accounts, plus Google Voice attached to the one email address. I used to use Gmail Notifier to do the Gmail portion, but I haven't installed it on the Galaxy Nexus yet. But what about Google Voice for texts, is that possible? Also if I could, I'd like to change the notification icons for each of the programs as well, something not so bland and grey, something more noticeable.

I have Light Flow also, works well and the only problem is it causes my books in the Google Books app to read aloud any time the app is first started.
