Info


Below the inputs, you may see this icon Digital Brain Icon.


This icon is next to the text that shows how we have understood what you typed into the box above it..
This shows up when the way we have understood your input may be different than how you typed it.
If what you type in is not a valid color, we will find the closest match.
For example, "gss111" will find the closest match, "gs 11".

This color calculator is specifically for calculating Maine Coon cat colors.

Coat colors with color point, chocolate, and cinnamon are not supported.

We parse eye color, poly, and coat length, but do not use them for calculations (yet).

  • Dominant: silver and gold are dominant traits; only one of the parents need to have silver/gold for their children to have silver/gold.

  • Recessive: dilute colors are recessive traits; both parents need to show/carry dilute colors for their children to have a dilute color child. Because dilution is a gene, it may not be visible in the parents. Dilute is also referred to as the lightening gene.

  • Special characters: not allowed. Do not use characters like "% $ # @ ! * ( ) ~ ? ."

    Valid characters: Please only use "abcdefghijklmnopqrstuvwxyz", numbers "0123456789", and optionally spaces/dashes (" "/"-").

  • Order: EMS codes should be in ascending order (lowest to highest).

White is a masking color.

Any color can be hidden under white, so kittens of almost any color may appear.

If you know the white cat's parents, you can predict the color of the kittens. Try using the parent colors in place of white to see the results.
