Sony Ericsson Xperia X10 :: Color ID App On SE

My SE is in Jacksonville and should be delivered in the morning, I would really like some help finding an app that works like Color ID on the Blackberry. It is simple and works with the LED notification, allowing you to change the color of the LED based on the source of an email.

I only need it for one thing, so it doesn't need to be real complex or handle allot of different numbers/email addresses, I just need it for when I am on-call for work.

When I receive a page (via email) in the middle of the night, I need to be able to tell it from some generic spam mail or mail from a long lost friend, so I only have to actually get up and read the message for work pages.

Seems simple, got to be an app that can do it, but searching the market for has not found what I need. it doesn't have to be just LED, could be ringtones (never used them before, my blackberry has been on vibrate forever), but anything, flash the screen, etc. Anything that will wake me up and make me realize it is time to go to work....
