Here is my Black TWH after using Paprika as a supplement. I should point out that I do not show, so I don't have to being concerned about "positive testing"..
When I bought her the owner showed me pictures of her when she was very black before she was so sun-faded.. I wasn't sure I would be able to ever her get her back to being a BLACK horse again...
In the first picture you will see that she is sorta bay, or brownish. I started using paprika in mid-March and you will see the difference in the second picture. - I also give her a small amount of Canola oil and Flaxseed to make her shiney.
I promise you this is the SAME horse. Hubby says it's amazing that she looks like a different horse.
