What are the least common colours on all cats?

It's tricky to definitively say which colors are the "least common" because cat color genetics are complex, and breed-specific color variations exist. However, some colors are generally less common than others:

Less Common Solid Colors:

* Lilac: A dilute version of lilac, often described as a light lavender.

* Chocolate: A deep brown color, often seen in certain breeds like Persians and Maine Coons.

* Cinnamon: A reddish-brown color, also less common.

Less Common Patterns:

* Calico: A tri-color pattern (black, orange, white), usually found in females.

* Tortoiseshell: Similar to calico, but without the white.

* Lynx Point: A pattern with dark points on the face, ears, legs, and tail, often seen in Siamese cats.

* Flame Point: A pattern with orange-colored points.

Important Notes:

* Breed Influence: Certain breeds are more prone to specific colors. For example, the Abyssinian breed is known for its "ticked" coat, which is uncommon in other breeds.

* Regional Variations: The prevalence of certain colors can vary by region. For instance, certain colors might be more popular in specific countries.

* Rarity and Value: Some rare colors, like the "Silver Tabby" or "Black Smoke," can be highly sought after by breeders and cat enthusiasts.

Ultimately, the "least common" colors are relative and depend on a variety of factors.
