I am unable to put chatcolor on minecraft, However when sending color &4 for exemple from Discord to Minecraft It works.

Discord doesn't have colors

are you sure you correctly read ? I said that when i type a colorcode in discord, the color shows correctly in Minecraft, however if i try to type a color code directly in Minecraft, it doesn't work anymore since i installed DiscordSRV.

DiscordSRV doesn't modify vanilla chat behavior

But when i remove the plugin, chat colors are working fine
