You are right obsidian is black and purple. Maybe your friend has a mod that makes it purple or maybe the color on your friends computer is messed up but if you want proof then you can google it
I tried googleing it, but all that comes up is: Obsidian. Made by mixing lava and water. Category: Building block. Or something like that, it just doesn"t come up with: Obsidian is (insert color) With thanks, Sparkz
