How to add a new horse type

When I tried adding an edited image of horse with red eyes, it did not appear. Even though I had renamed it (horse_black1). When the original horse, (horse_black) was deleted and replaced by the edited, it worked fine. The problem with this was that no normal black horse could appear. Does Anyone know how you can have both types of horses without losing any variant, just adding a new one?

You can't add a new horse type without modding the game, you can just edit it using resource packs (like you did).

You would have to get rid of at least one. Instead of replacing the black one you could replace a different colored one if the black one is important in your world.

You could also use skeleton or zombie horses because they are not original and have to be summoned. You can change there texture instead then spawn them with these commands:

Tamed Zombie Horse: /summon EntityHorse ~ ~ ~ {Type:3,Tame:1}
Untamed Zombie Horse: /summon EntityHorse ~ ~ ~ {Type:3}
Tamed Skeleton Horse: /summon EntityHorse ~ ~ ~ {Type:4,Tame:1}
Untamed Skeleton Horse: /summon EntityHorse ~ ~ ~ {Type:4}
