hey!
I'm glad your interested! I'm still working on this group and breed so it's not totally completed yet, but you are very welcome to create your own espino!
The horses can have all colours, but notice that it's not possible to create a black horse with black markings or white horse with white markings. Also a totally white horses with black markings and black horses with white markings are rare and you can't create them yourself
But it is possible to create a grey horse as long as it's not totally white
If you have made a reference you can send it to the registrated mares or stallion folder depending on the gender of your horse
If you have any more questions, feel free to ask
