ChatColor lets players change the color and style of their chat.
Legacy colors, hex colors, rainbow colors and gradients are supported.
Works on Spigot, Paper and Folia. The plugin is built against the latest Paper API line (26.1.x) and still keeps support for older Minecraft versions back to 1.8.x where the Bukkit API allows it.
Folia support is built in, with scheduler handling split for Spigot/Paper and Folia servers.
