So I was playing around in photoshop recoloring stuff when suddenly decided to try maroon color in different markings than the ones available. And it went extremely well. So I tried a few event colors on breed-only markings, and it went even better.

So my suggestion is to maybe add some special colors to special markings. They'd be highly rare, of course, but since I'm still not that much into breeding I'm not sure of the way they could be included in the game and passed through breeding, so that point is open to more suggestions as well as any other.

Extra suggestions:
— Dawn Iris (#40323): This would be an awesome event or raffle idea!
— Rusty [MP] (Quad celestial) (#39276): It could be like what happened to introduce tsavo but for a day and/or week only? I can't remember very well, but there was a different stud every day with tsavo mane on the news page and you could stud your lionesses in heat to them (for a fee i think) with the chance of the mane passing on to the cubs ^^ that's how it was introduced to the game
— Jaytsa -Ships Lions!- (#36189): Loving that infernal lace. Perhaps it could be added to a weekly special lioness or implemented into a monthly event (Halloween????)
