Using the following command:
/give @p minecraft:stone{display:{Lore:["{\"text\":\"T\",\"color\":\"yellow\",\"italic\":false}","{\"text\":\"e\",\"color\":\"red\",\"italic\":false}","{\"text\":\"s\",\"color\":\"green\",\"italic\":false}","{\"text\":\"t\",\"color\":\"blue\",\"italic\":false}","{\"text\":\"\\n\",\"color\":\"none\"}","{\"text\":\"JSON\",\"color\":\"white\",\"italic\":false}"]}}
[media]Either I didn't format it correctly, or there's an underling issue.
Just as before, each piece of
Lore
appears on a new line, so you want a single text component all in oneLore
entry rather than 5 separate entries (because that's 5 separate lines).I went ahead and fixed it for you 🙂
