This resource pack tweaks the appearances of Iron Horse Armor, Golden Horse Armor, and Diamond Horse Armor in a couple small ways:
Leather Saddle Pads
All horse armor variants now use the warm-brown saddle pad which was originally exclusive to Leather Horse Armor.
Updated Color Palettes
The color palettes used for Iron Horse Armor & Diamond Horse Armor have been changed to match their player armor counterparts much more closely.
This primarily affects the Iron Horse Armor, which is now a lot lighter! The color palette used for Diamond Horse Armor only needed small tweaks, making the difference much harder to notice.
Golden Horse Armor already shares its color palette with the Golden Armor worn by players, hence its exclusion.
