When/how is orange unlocked?

I know orange is on some servers, but how do I know when on mine?

To know if your Server has the Orange Rarity, just check via Heroes > Random Hero > Items > Badge List

[Filadae_Djaq]

The most recent level you can get orange heroes are at level 83. If your server’s level cap is 85, you will be able to get an orange hero

I’m on server 18

After Purple +4 is Orange +0.

Orange does nothing, it just change colour border around hero icon.
It doesn’t give any new skills or special stat boost.
