Wondering what colours a Siamese pairing could throw? This free Siamese cat colour predictor does the genetics for you. Choose each parent’s genes — base colour, dilution, the caramel modifier, red and tabby — press Calculate, and it returns every possible kitten colour with its probability, using GCCF colour names.
It’s a quick way to sanity-check a mating before the kittens arrive. Not sure what a parent carries? Open the How to use this predictor panel inside the tool — it explains that base colour and red are separate genes, and how each setting maps to what you see in the cat.

Want to understand the genes behind the result?
The predictor models the same handful of genes that make up every Siamese colour. To see what each one looks like on a real cat, browse the Siamese colour chart and the individual colour pages in our Siamese breed profiles. For the genetics themselves — how colour is inherited, what “carrying” means, and why two seal points can have lilac kittens — see our Siamese cat genetics guide.
