As the title would suggest I would like it if someone could point me the right direction when it comes to sending an item's data to the client.

Purpose & Example: Item's charges value like chaotic rapier with 1408 charges would have the number 1408 sent to client. After charges go down to about 1000, the coloring of the rapier is slightly darker.

If I explained that badly, here is another example. Let's say I attach a value of 500 to a completionist cape, and when that value is shifted, the color of the cape is shifted as well, but in order to do that, the number would need to be sent to the client.

My brain is fried currently from coding this value system so I'm a little confused and cannot figure out how to send this data to the client.
