mColor applies colors directly through Adventure, so PlaceholderAPI is optional. H2 and safe defaults work immediately, while shared SQL storage, presets, temporary event colors and public copying can be enabled deliberately.

What it does

• Strict #RRGGBB input, configurable named colors, rainbow mode and gradients with up to sixteen stops.
• Localized inventory pages for basic colors, adjacent gradients and server-defined presets.
• Direct display-name and player-list rendering on Paper, Purpur and Folia.
• Permanent or temporary colors with automatic expiry for online and offline players.
• Personal history with an atomic /color undo operation, including restoration to no color.
• Privacy-first /color copy: copying is private by default and must be enabled by the target player.
• Administrative set, temporary, reset and inspection commands for online players.
• Optimistic in-memory updates with serialized SQL writes and revision-aware rollback.
• H2 by default, plus SQLite, MySQL, MariaDB and PostgreSQL with automatic schema upgrades.
• Optional shared-database polling for server networks.
• English and Russian messages, Java Services API, PlaceholderAPI, bStats and granular permissions.

Quick start

1. Put mColor-1.1.0.jar in the server's plugins directory and restart.
2. Grant named colors or special effects through your permissions plugin.
3. Run /color gui or /color red.
4. Adjust palettes, presets and limits in plugins/mColor/config.yml when needed.

The default H2 configuration requires no credentials or external services. If explicitly configured external storage is unavailable, mColor starts in memory-only mode and logs the cause.

Player commands

Command	Description
/color gui	Open the localized color menu
/color <name> or /color #RRGGBB	Apply a solid color
/color gradient <color1> <color2> [color3...]	Apply a multi-stop gradient
/color preset <name>	Apply a configured gradient preset
/color rainbow	Apply the rainbow profile
/color temporary <duration> <profile...>	Apply a temporary color; durations use m, h, d, or w
/color preview [profile...]	Preview without changing the saved profile
/color history	Show recent settings and expiry information
/color undo	Atomically restore the previous setting
/color privacy <public|private>	Allow or deny other players copying the active profile
/color copy <online-player>	Copy a public active profile and its remaining expiry
/color reset	Restore the normal name

Administrators can use /mcolor set <player> <profile...>, /mcolor temporary <player> <duration> <profile...>, /mcolor reset <player>, /mcolor info <player>, and /mcolor reload.

Permissions

Permission	Default	Purpose
mcolor.use	everyone	Use /color and the GUI
mcolor.color.<name>	unset	Use one configured named color
mcolor.color.*	operators	Use every named color
mcolor.hex	operators	Use arbitrary strict hex colors
mcolor.gradient	operators	Build custom gradients
mcolor.preset.<name>	unset	Use one configured preset
mcolor.preset.*	operators	Use every preset
mcolor.rainbow	operators	Use rainbow mode
mcolor.temporary	operators	Apply temporary profiles
mcolor.copy	everyone	Copy public profiles
mcolor.copy.bypass	operators	Ignore target copy privacy
mcolor.history	everyone	View and restore personal history
mcolor.admin	operators	Manage players and reload configuration

The GUI enforces the same named-color, preset, gradient and rainbow permissions as commands.

Language and configuration

English is used by default. Set language.default: ru_RU and run /mcolor reload to switch to Russian. Set language.per-player: true only when the interface should follow each player's Minecraft locale.

limits.maximum-temporary-days bounds temporary profiles. History display size, retention and expiry checks are documented under history. Copying is private by default through privacy.copy-public-by-default: false.

PlaceholderAPI and Java API

• %mcolor_name% — legacy-colored player name
• %mcolor_name_mm% — escaped MiniMessage rendering
• %mcolor_name_stripped% — plain player name
• %mcolor_color%, %mcolor_color2% — first and second colors
• %mcolor_gradient% — all render colors separated by commas
• %mcolor_has_color% — yes or no
• %mcolor_of_PlayerName% — another online player's colored name

All placeholders use the in-memory cache and never query SQL on the server thread. Other plugins can obtain MColorService through Bukkit's services manager.

Storage and networks

The schema records active profiles, expiry, privacy, bounded history and cross-server invalidations. Changes are transactional. SQL tasks are serialized to preserve command order, while revision checks prevent an older failed write from rolling back a newer selection.

For a network, choose MySQL, MariaDB or PostgreSQL on every backend, use the same database, assign a unique sync.server-id, and enable sync.enabled. Old invalidation rows are cleaned automatically.

Telemetry

mColor uses anonymous bStats metrics when metrics.enabled is true. No UUIDs, names, colors, history, privacy settings or database credentials are collected. Disable metrics in the plugin configuration or the global bStats configuration.
