Currently, there are 4 ways to get more Dye Kits:
1. Go to your Craft Shack, select a craft to make that requires Dye Kits. If you don’t have any, click on the blue “Ask” button under Dye Kits and select some friend.
2. Watch ads in the Vintage Projector and earn mystery prizes
3. Buy them with Ranch Cash from the OPs tab in the Shop
4. The Cheap Train will also sometimes randomly give you Salt, Pepper or Dye Kits when you completely fill a crate
