I renamed my speed horse and the name is no longer orange, when I renamed my jump horse the name is orange
It's impossible The orange text is there to make it valuable and prove its real, unfortunately if you rename it you can't get it back
I don't think you can get the text back. If you really want it then try putting the name back to how it was. That is weird that the jump kept his orange color.
Well it had some weird characters when I was renaming the speed one and I deleted them not realizing they kept orange colors
