Item view of trim has wrong color

[Ayutac]

Minecraft version: 1.20.1
Loader version: 0.15.11
Mod version: 2.1.2

Describe the bug
I can trim the armor with a custom material alright, but the color of the trim lines in the item view isn't correct.

To Reproduce
Steps to reproduce the behavior:
Reproduced the kelp pack with a custom item and other colors.

Expected behavior
I expected the color lines to be golden, not grey, i.e. use the provided color that is correctly displayed in the tooltip.

Any reason why you aren't using the latest 2.1.4 version? As to this issue, I'm pretty certain this is due to the model loading api changing in FAPI. I'm pretty certain I had fixed this though with the latest 1.20.1 version

Bug is still present in 2.1.4
