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.

Final state
Untouched pixels
Pixels that were never placed on (also referred to as virgin pixels), depicted in white. Pixels that could not be placed upon are depicted in a deep maroon color.
Pixel age
Age of pixels as a brightness map. Darker pixels were placed longer ago.
Heat map
Depicting activity on the canvas as a heat map - the brighter a pixel's color, the more often it was placed on.
