ItemHighlighter

Hold an item, give it a color, spot it instantly. Highlighted items get a glowing outline in the world (dropped items and item frames), a tinted item texture in the hotbar, inventory and containers, plus a colored ★ Highlighted tooltip line - in your inventory, in chests, in your hand, everywhere you look at items. Client side, no keybinds.

• /hl #RRGGBB highlights the held item type (legacy &/§ codes work too), /hl clear removes it, /hl list shows all
• Per-item-type highlights with custom colors, persisted across restarts (matchComponents narrows it to the exact held item)
• Config: enabled, defaultColor, showTooltipLine, hotbarHighlight, matchComponents
• Requires Mycel: install it alongside this mod

Reload live with /mycel reload itemhighlighter.
