Shiny Show Tack...
Western Pleasure Set!
I need you to read some things so you don't freak out or get confused when you first see these in game. They're deceptive.
If you don't read any of this and freak out, I'm sorry but I'll send you back here.
When you first look for the tack in your accessories, all of the items will show up as one color duplicates in game, or a blurry breast collar.(picture above) When you click on any of these, they will appear to be just a duplicate, they won't look special, do not fear, I did not fail you! Just go straight into the color editor and change any of the channels to the color of your choice, like magic the piece of tack will transform into the image on the right.
Half of this is because I forgot how to figure out how to change the images you see and click on for the tack :L If you know how, tell me?
None of the silver is recolorable :c sorry, they changed colors with the tack, so they're all masked over permanently. You can edit the color of the leather, that's all. Each item will have all the normal channels, but only one will work. The saddles fourth channel, the bridles first channel, and the breast collars second channel. The pad will work perfectly and both channels can be edited. Have fun.
Oh right, the bridle only shows up in every day.
