Not sure if i understand you correctly, but i think you can just use data merge entity @e[type=item_display] {CustomName:{"color":"dark_aqua"}}

It does not change

The full json with the text and color combined

#

Which version are you on?

#

Ah 1.21

#

Yeah you can't directly do that then

#

Probably what you'll have to do is copy the name to an item, then use an item modifier to set the colour, then copy it back

How would I set the custom name color using an item modifier without changing the name?

faint wind Jun 26, 2025, 7:59 AM

#

You can essentially copy the existing name while changing the colour. Here's an example from a datapack I made a while ago:

{
  "function": "set_name",
  "entity": "this",
  "target": "custom_name",
  "name": {
    "color": "aqua",
    "nbt": "SelectedItem.components.minecraft:custom_name",
    "entity": "@s",
    "interpret": true
  }
}

#

Basically, it copies the previous custom name but with a new coluor (aqua in this case, but it can be whatever)

How would I copy it back?

rotund gyro Jun 26, 2025, 2:46 PM

#

it's all a single step. It copies the name with a different color from itself to itself.

But this is an item modifier, how would it work on a display

rotund gyro Jun 26, 2025, 7:25 PM

#

item displays have an item inside them

abstract holly Jun 26, 2025, 7:26 PM

#

So item modify entity @s ??? Namespace:change_name

#

#

content

#

item frames, item displays, and all those things use the content slot

abstract holly Jun 26, 2025, 9:39 PM

#

rotund gyro content

I'll practically check in mc, but content does not seem to appear on mcstacker

rotund gyro Jun 26, 2025, 9:42 PM

#

What did you check in mcstacker?

#

there is no place on mcstacker where you would use/check that

#

if you use the item command in mc it should even suggest that as an option

abstract holly Jun 27, 2025, 5:58 AM

#

it shows up in-game, tysm!

#

Am I doing something wrong?

#

It's still aqua

abstract holly Jun 27, 2025, 6:27 AM

#

It is the item display itself that has the name "Water"

rotund gyro Jun 27, 2025, 6:42 AM

#

Yeah, you only modified the name in the item. The item modifier does copy the name that it modifies to itself but you still have to copy it over to the entity.

Would something like this work?

data modify entity @s CustomName set from entity @s Item.components."minecraft:custom_name"

rotund gyro Jun 27, 2025, 3:42 PM

#

yes

abstract holly Jun 28, 2025, 5:33 AM

#

I'm not sure what is different, but now it does this

#

#

  "function": "set_name",
  "entity": "this",
  "target": "custom_name",
  "name": {
    "color": "green",
    "nbt": "SelectedItem.components.minecraft:custom_name",
    "entity": "@s",
    "interpret": true
  }
}```

#

/execute as @n[type=minecraft:item_display] run data modify entity @s CustomName set from entity @s Item.components."minecraft:custom_name"

#

And when I run this ^ command it does nothing

faint wind Jun 28, 2025, 6:45 AM

#

Ah if you're changing the contents rather than the mainhand of an entity, you need to change the item modifier slightly

#

Instead of SelectedItem.components, it needs to be item.components. That will copy the name from the item held by the item display

abstract holly Jun 28, 2025, 9:53 AM

It does not work 😦

faint wind Jun 28, 2025, 10:25 AM

#

Oh well if there's no name in the first place, then yeah it can't copy the name

#

You need to copy the entity name to the item name first

#

Actually you just need to modify the item modifier a bit again. Replace item.components.minecraft:custom_name with CustomName

That breaks it

#

After some attempts, I realised that it is getting a color without a custom name

#

So its not copying the custom name of the item display

I still can't get it to work

Someone help pls

#

Looks like you're missing "interpret": true in your item modifier. Not sure if that's what's causing the issue

#

I'll try to test today on my computer to see if I can get it working

abstract holly Jun 30, 2025, 9:12 AM

#

What does interpret do?

faint wind Jun 30, 2025, 9:46 AM

#

The custom name looks something like this: {"text": "Water", "color": "green"}. Interpret basically means instead of reading that string as it is, it tries to understand what it means (in this case the text is "Water" and the colour is green). Then it can properly apply transformations without breaking the existing data (so the colour changes to aqua but the text stays as "Water")

abstract holly Jun 30, 2025, 9:08 PM

#

It unfortunately still has no effect

faint wind Jun 30, 2025, 9:30 PM

Yeah I couldn't get it to work. Maybe that code is from a previous version

#

I'm not sure if there's another way to do it
