How to specify spawn entity arguments

[tryce404]

I'm trying to figure out how to specify NBT parameters when spawning an entity. mc.spawnEntity(x,y,z, SHEEP, "{Color:1b}") How do you change color of sheep when spawning???

It's not possible to specify colour. spawEntity make use only four of it's argument: coordinates and entity_id.
Even if you pass more params, it won't be used.
