Rainbow Brick

Rainbow Brick is a Hardmode brick that can only be obtained as a drop from the Rainbow Slime. They cycle through the colors of the rainbow. The cycling colors of Rainbow Brick Walls, Rainbow Torches, the Disco Ball and Rainbow Hair Dye are synchronized with each other. When a waterfall passes over a Rainbow Brick, hammered once, the water will also cycle through the colors.

Next to Lihzahrd Brick, Rainbow Bricks are one of the hardest blocks to obtain, being that they never occur in the environment, cannot be crafted, and only drop from Rainbow Slimes. Despite this, Rainbow Bricks still only have a rarity of white (second lowest only behind gray which only applies to trash items like the Old Shoe and white tier tools with negative modifiers).
The aesthetic of the brick, when placed, will either have the rectangular appearance of a standard brick, such as a Gray Brick, or a uniform blank appearance, such as that of a Smooth Marble Block. It may also change between one and the other when hammered. This can make it a rather tedious building material to use.
Rainbow Bricks will still maintain their rainbow-glowing effect even when painted.
