Luminous Owl is a gorgeous burnt orange. It is the most unique color in the Hertiage collection. The camera seemed to have captured it as more of a rich orange but it's more of a burnt orange in person.

I decided to compare this against the only other orange holo I own which has been discontinued.
I compared it against Enchanted Polish - Sour Patch Kid.
Sour Patch Kid is a richer orange with a slightly stronger holo but Luminous Owl is a better formula and easily obtainable. They aren't dupes but they are close enough that you wouldn't need both. If you missed out on Sour Patch Kid, Luminous Owl will fill your void. :D
