HEX colors are not showing properly when using player.spigot()#sendMessage(ChatMessageType, BaseComponent[]) to display an actionbar. It seems it's applying the color code from the last char in the hex string. (#FFFFF4 = §4), however using the vanilla title command with json text displays the colors properly. I've also tried using ChatColor#of(String) and TextComponent#fromLegacyText(String) but with the same issue.

Tested on git-Spigot-16d7899-4ff609e, 1.16.1-R0.1-SNAPSHOT

Here's an image of two calls using the same TextComponent but one sends to ActionBar and the other to the chat.
