whats the command to see white outlands of entity in minecraft potion

Use this command to make an entity glow white in Minecraft Java:

mcfunction

/effect give @e[type=<entity>] minecraft:glowing 999999 0 true

If you want it to apply to all nearby entities:

mcfunction

/effect give @e minecraft:glowing 999999 0 true

Notes

• minecraft:glowing is the effect that creates the outline.
• The outline is white for most entities unless they are on a team with a colored glow.
• true hides particles, which makes it cleaner.

Example

To make all zombies outlined:

mcfunction

/effect give @e[type=zombie] minecraft:glowing 999999 0 true

If you meant a different version of Minecraft or a command to make a potion item that gives glowing, say which edition you’re on.
