I know there are already Siamese color markings in the game, but I think it would be interesting to have it as a mutation that corresponds to how the siamese works in real life. It could be called Thai Mutation. This would work almost like a reverse siamese coloring and would allow for the "points" to be patterned, and in older age any darker patterns will show through on the body as well.


How does it work?
For this example there'll be increased cub stages and I'm gonna use a dark brown (black) base and no markings:

- For the first stage the cub will be completely white.

- In the second stage it begins showing a little light brown around the nose, the rim of the ears, the toes and a darkening of the tail tip and light coloring on the tails base.

- The third stage will have a full colored face, dark ears, dark feet and dark tail. But none of the dark points overlap.

- The adolescent will have the colored areas spread a bit further, and have the same spreading of color as the adult, but the white will still be 100% opaqe on the body.

- The adult will have ~98% Opacity on the white parts of the body between age 2-5. This will make the lion show its base color faintly through. Then it drops 1% Opacity every year until the age of 10 when it drops 3% a year for the remaining time alive.

For the males their manes will remain white since it protects against the cold, which is what triggers the pigmentation to appear.

For a more thorough explanaition on how and why the siamese looks the way they do I'll refer you to this article by Robyn Broyles.


Excerpts from the article:

Siamese cats have a unique coat pattern. The gradual shading of the extremities is caused by a recessive gene with temperature-sensitive expression. The resulting pattern is essentially a heat-map of the cat's body.

Pointed cats are partial albinos. Albinism is a mutation in theTYR gene, responsible for the enzyme tyrosinase. Tyrosinase, in turn, is necessary for the production of melanin, or dark pigmentation.

The albino mutation in Siamese cats results in a defective form of tyrosinase which does not function at normal body temperature. Therefore, dark coloration can only appear in parts of the body that are cooler than the core body temperature. The extremities are always the coolest parts of the body. The face is also cooler because of air passing through the sinuses. The back is warmer than the extremities, being closer to the body core, but it is also exposed. The result is a medium degree of tyrosinase function, resulting in a medium degree of shading.

The original mutation occurred centuries ago in Thailand (formerly Siam), but the details of the history of the Siamese cat are cloaked in mystery.

How to get it:

The Thai Cat Mutation can be passed down from Lions to cubs in two variations. As a Thai Lion, or as a Carrier. Those not affected are Non-Carriers (all Lions currently on Lioden would be this).

- Two Thai Lions will always produce Thai Cubs - No exeptions.

- One Thai Lion with a Thai Carrier will get a Thai Cub 10% of the time and a Carrier 20% of the time. The remaining 70% will be Non-Carriers.

- Two Carriers will produce a Thai Cub 1% of the time and a Carrier 5%. Leaving 94% of cubs as Non-Carriers.

- A Carrier and a Non Carrier CANNOT produce a Thai Cub and only produce a carrier 1% of the time. 99% of cubs will be Non-Carriers.

- A Thai Lion and a Non-Carrier cannot produce a Thai cub but can produce a Carrier 10% of the time. 90% of cubs in this pairing will be Non-Carriers


As for how the first lions carrying the trait shows up on the site, it could be a low chance of a NCL being a carrier. That way, no Thai Lions would show up without at least a little bit of effort while breeding, and it would be difficult but not impossible to introduce new and rare colors. It would also not be exclusive to veteran players.

I hope I got the general idea across. Thanks for your time!
