Skyicon

Skyicons are small pixel-icons following specific rules.

For example, they can be used as placeholders for profile pictures.

Rules

• Corners have to be colored
• Squares of 2x2 of the same color are not allowed
• There must be 3 separate surfaces each min. 4 and max. 10 squares in size
• When there is a diagonal line, one of the line's corners has to be colored

Fingerprints

Every Skyicon can be identified by its unique fingerprint which is a 9-digit hexadecimal number representing the 6x6 pixels.
