• You didn't use /reload

Describe the question
How can I HEX colors in use the PLAYER_INFO UPDATE_DISPLAY_NAME packet? I am trying to update the player's display name in TAB using HEX but only the last color code will appear. If, for example, I have §x§F§9§F§1§8§9Name, the name will be blue because the last code is §9.

API method(s) used
ProtocolLibrary.getProtocolManager().sendServerPacket(player, packet);
Where packet is the PLAYER_INFO packet.

Expected behavior
The name in the tablist should be HEX.

Code
The packet that is being sent -> https://pastebin.com/cXw4DPQE
"newName" is the name that has the color codes. For example: §x§F§9§F§1§8§9Name

Additional context
I've tried using an external TAB plugin and placeholders and it did work, it only doesn't work when using packets.

You need to use WrappedChatComponent, from a legacy text (like you have) or, with a way more cleaner way, from json, e.g. with Adventure API (also work with the json serialize of BungeeCord chat api) :

private static PlayerInfoData getPlayerInfoData(Player player) {
    return new PlayerInfoData(WrappedGameProfile.fromPlayer(player),
            player.getPing(),
            EnumWrappers.NativeGameMode.fromBukkit(player.getGameMode()),
            WrappedChatComponent.fromJson(GsonComponentSerializer.gson().serialize(player.playerListName())),
            WrappedProfilePublicKey.ofPlayer(player).getKeyData());
}

Thank you very much, this fixed my issue!
