How formatted colors work in Hytale
Hytale server messages use structured Message objects rather than one universal text code. The native API can combine colored child messages and apply supported styles, while libraries and plugins define their own input formats.
Native Message API example
The generated Java uses Message.raw, color and Message.join so each gradient unit becomes a valid child message.
Message styledText = Message.join(
Message.raw("H").color("#F1B72F"),
Message.raw("y").color("#D8C75D"),
Message.raw("t").color("#65B7D8")
);
