LED Notification Colors

I am still new to this phone.. but i'm trying to find out if the LED light allows for more colors than just Green and Amber ?

I had tried LED Light Manager and it didn't seem to make other colors..

Now that i'm rooted and running Viper ROM.. I see that they only have options for "apps to use amber instead of green"...

so does that mean that is the only color options?

Thanks!
