Try SMS pop up. I like the stock Bionic sms app and like a popup for convenience. I was pleased when I found the free sms pop up can change the color of your LED. Cyan, orange, green so far... still testing Blink free app works as well, but I don't know what colors I assume the same.
I actually set my dad up with Light Flow Lite, after he complained about not having different sounds for different notifications, as well as colors. Works very well, but I like one tone.
