Dark Black is a color in Club Penguin. It is not available in-game, but is used as a placeholder for games designing, where the color is later picked by the penguin's color. It can sometimes be seen through glitches.
There are a few Mix-And-Match figures that appear to be Dark Black.
In Club Penguin's videos on the old main page, Old Blue and Dark Black penguins were animated on pictures of Club Penguin.
 The penguin on the cover Lime Green Dojo Clean is Dark Black.
A few penguins in My Puffle are Dark Black.
This is the only color in Club Penguin that has no shadow value.
The color can be obtained for a few seconds by wearing some items (not all work) and changing from color to color really fast, if you don't move, you can be dark black for a limited period of time.
