Gleam

Gleam is a luminescent Block that emits light. The light emitted by a gleam block is correspondent to the block's colour. Different colour versions of gleam can be found in nearly all servers of the Oort Universe.

They can be found on surface, inside caves, under floating islands and underwater. They can appear in single blocks, spikes, clusters, or massive gleamballs.

Varieties
Gleam has 255 colour variants, some of which are listed below, each emits light of that colour. Gleam will drop as an item when broken with any tool, though the Hammer seems to be fastest tool for the job.
