I want to fill an area with black concrete in Minecraft (Java version, 1.12), but I have no idea how it should work. I know? Of course, the command [/ fill ~ ~ ~ ~ ~ Minecraft: black_concrete] but that does not work in 1.12 with black concrete or other colors. Still, that should work, hopefully.
/ fill ~ ~ ~ ~ ~ ~ minecraft: concrete 15
If you hover over the black concrete in your inventory, you are sown:
Black Concrete (# 0251/15)
Building blocks
minecraft: concrete
For the other colors, other numbers are after the '/'
For example, it is the 14th for red
