ToySoft has a long history of making LED control apps for BlackBerry. They just brought their Color LED Message app to BlackBerry 10 that lets you easily customize the LED color for incoming calls, SMS, email, accounts, no network, and ringtones. There are 27 colors to choose from so you should have enough to keep you busy it also lets you set keyword filtering, custom blinking duration, and custom vibrate duration. Like all other current BlackBerry 10 notification apps Color LED Message sadly needs to be running for it to work. Hopefully BlackBerry gives devs a way around that soon!
