Canvas is a decorative block that allows players to draw custom 12×12 pixel images in-game. Interacting with a placed Canvas opens an editor showing a 12×12 grid and a pencil button to begin editing. The editor provides a palette of eight colors, a bucket tool to flood-fill contiguous pixels, and a button to hide or show the pixel grid. Clicking a pixel paints it with the currently selected color; edits can be committed with a save button or discarded with cancel. Multiple Canvases that are placed with perfectly aligned sides join together, removing the border between tiles to form a continuous image.
The Canvas supports the following eight colors (hex): 362944, c45d9f, e39aac, f0dab1, 6461c2, 2ba9b4, 93d4b5, f0f6e8. A newly placed Canvas has all pixels initialized to 362944.
Canvas is Erekir-exclusive content. It was introduced in Version 7.0 and later adjusted in Build 146 when its silicon cost was reduced from 30 to 10.
