Create a Basic Item Tooltip with Custom Text and Colors

Set Up Your JSON File

Create a new file at assets/yournamespace/datatip/datatip.json inside your resource pack folder. This is where all your tooltip definitions live.

Define Your First Tooltip

Start with a simple structure:

`json

{

"tooltips": [

{

"match": "minecraft:diamond_sword",

"lines": [

{

"text": "A powerful blade",

"color": "#FF5733"

},

{

"text": "Deals extra damage",

"color": "#FFFFFF",

"bold": true

}

]

}

]

}

`

Replace yournamespace with your mod or pack name. Use the match field to target item IDs exactly.

Apply and Test

Press F3 + T or run /reload in-game to refresh your resource packs. Hover over the matched item in your inventory to see your custom text appear with your chosen colors and formatting.
