Many know the & color code (for example & a & l). Can you add your own colors? So there are given colors and I want to add more. Is that somehow possible? Spigot 1.15.2
Maybe that works with mods but not with Vanilla Minecraft.
I have Spigot 1.15.2
If you have a server, you could try programming something like that. I don't know much about it, but try a tutorial for a chat administration plugin.
