The colorful lamps addon uses the cool new 1.12 update features that give you the ability to create your own blocks, like you used to be able to do with the mods on the old versions of the game (back around 2013-14) with blocklauncher for android. Now, this is a feature that doesn’t require any mods or mod launcher.
Above, you can see the yellow stained lamp on the left, and the original lamp on the right. These are quite similar, which is good at showing the differences. The stained lamp is using a darker frame, while the original is using a lighter, and more pink texture. This might be due to the exclusive shaders that we use for screenshots.
