Inventory Highlighter (HighlightRender)
by FelixFGF
Inventory Highlighter colors item slots in the player inventory by item type, enchantment and custom rule, so important stacks stand out at a glance.
What it does
Inventory Highlighter marks slots in the inventory screen with colored outlines. Each rule can match an item type, a set of enchantments or a custom condition, and the matching slots take the color set for that rule. Rules are evaluated in priority order, so a higher rule can override a lower one when an item matches both.
The mod is a client-side rebuild of an earlier highlighter, brought up to date for newer Minecraft versions with better performance and more customization. Fabric API and YetAnotherConfigLib (YACL) are required, and Mod Menu is optional for opening its settings screen. Builds are published for the newest releases, with the latest Fabric file at 1.4.3 for 1.21.4, dated 2026-09-15.
The mod is released under the MIT License but is not open source. Only the client needs it, so servers run without it and players can use it on any server.
Key features
Colors by item type
Different item types can be assigned different highlight colors, so tools, food and rare gear can be picked out at once.
Enchantment highlighting
Enchanted items can be marked separately, making it simpler to find gear with the enchantments a player cares about.
Custom rules and priorities
Players write their own rules and set priorities, so a rule for rare items can take precedence over a broader rule.
Adjustable colors
Highlight colors can be changed per rule, letting each category keep a distinct look during inventory sorting.
