Every Natcat has a unique color combination determined by the values present in each digit of its Bitcoin block number. Each digit controls the color of a specific component of the cat, with each numerical value returning a specific color.
For example, the last digit of a block number determines the cat’s face color. In block 624487 the last digit is 7, which returns the color green, so this block generates a cat with a green face. Similarly, in block 624478, the last digit is 8, which returns the color pink, so the cat generated from this block will have a pink face.
The following variations can occur in the Natcats collection.
