What color tack would look best on my gelding?

I'm looking for general opinions on tack color for my gelding. He lightens (more red) in the summer and darkens (almost liver chestnut color) in the winter. I've taken a peek at the hobby horse color chart, but am more interested in black, light oil, dark oil, etc. tack color choices :)

Any helpful opinions are appreciated! Thank you!

He certainly is a pretty boy! I think he'd be pretty in any color tack but the light reddish colored tack would be gorgeous on him

Those highlights scream "Orange would look amazing!" to me :3

Light oil - to match and bring out his gorgeous forelock color. It would contrast with both his summer-red and winter-chestnut.

Two of our favorite color combos on a sorrel is Chocolate Brown with Amber accents or Hunter Green. Caramel Brown is another great color option too.

Thank you all for your great responses!

Oh yeah, I love the sweet look on his face. What a cutie patootie!

I was just gone say that! He does have a very sweet face! Very pretty boy!
