    Project mention: What plugin was this and how did they do it? | | 2021-07-16

    Hex codes were added in 1.16. Most chat for matters support them. You can use the search term “Chat formatter” when looking for a plugin. I like a specific fork of VaultChatFormatter, though it doesn’t have too many features. A good choice if you’re using essentials would be EssentialsChat. There are some other pretty nice chat formatting plugins online that I don’t know off the top of my head.
