How many available colors in Galaxy s7 notification LED?

[AC Question]

I just got a Samsung Galaxy S7 a couple of days ago, and the notification Led is something I find very useful. In my old S4 I only had green, blue and red (and combinations... purple and pink basically). But I find in my new S7 i just have the same colors. Tried to change to white in whatsapp but the led flashes in soft purple.

I can't find any documentation in the internet about the available colors in this device. Can anyone help me with this?
