Canvas 21a / 2019/04/01 ... 2019/04/04

> Canvas 22


Canvas 21a was an April Fools canvas. The canvas used "50 Shades of Gray" as a palette, allowing for well-shaded greyscale arts to be built.
In addition, the cooldown between being able to place pixels was reduced to 25%, which for most of the canvas meant a 7-8 second cooldown. The last half hour of the canvas had a fixed cooldown of 3 seconds.

On this canvas, except for a short while at the beginning, pixel lookups would only display the username -snip-, thus making it impossible (except for Mods) to say for sure who may be building, or attacking, a piece of art.
