Elevators allow you to create seemless builds without the need for stairs or ladders. If you want to go down a level, shift on the elevator. If you want to go up a level, jump on the elevator!
The only way to obtain elevator blocks is by crafting them. When using the crafting recipe down below you will get 2 elevator blocks. To change the colour of your elevator just put the blocks into a crafting table with the dye of your choice. Beware that all elevators must be the same colour for them to work together.
