Change Armour Colour based off of NBT Tag (Like Leather Armour)

[iiJowonny]

Hi, first of all apologies for my inexperience with modding in general but..

Could somebody help explain how I could change the colour of a piece of armour based off of its NBT colour tab (along with it's item), just like how leather armour works in vanilla.

I'm doing this in 1.20.1 using GeckoLib for my armour. I've already got the NBT tag bit working I just need help/ideas of how to make the colour change work.

I can provide what code I do have however most of it is from this tutorial: https://www.youtube.com/watch?v=3zqxU7vjHmQ&ab_channel=ModdingbyKaupenjoe

Thanks for any help you can give
