</details>##### **Red Dun Brindle with Sooty Plus (S+)**

Sooty Plus (S+) shifts around pigment to give a dappled look. This pigment shift, while darkening the horse, can distort the appearance of Dun Factor, in some colors making it almost invisible to see.

</details>##### **Red Dun Brindle with Dilution Genes**

Diluting genes change the intensity of pigment on a horse. This weakens the expression of Dun Factor, and in some cases it can be invisible.
