Caused by #3908. That PR has an issue, usages of ChatColor#parseHexColor expect the input to optionally start with a #, for example:

Skript/src/main/java/ch/njol/skript/util/chat/ChatMessages.java

Lines 280 to 283 in 9cc0164

	boolean tryHex = Utils.HEX_SUPPORTED && color == 'x';
	ChatColor chatColor = null;
	if (tryHex && i + 14 < chars.length) { // Try to parse hex "&x&1&2&3&4&5&6"
	chatColor = Utils.parseHexColor(msg.substring(i + 2, i + 14).replace("&", "").replace("§", ""));

But the regex check doesn't account for this, this fix makes it so it does.
