It's a little hard to tell Because My Scanner & Copier are Not kind to My Art or colored Pencils, But The Two versions are two difference shades of white.
Omni Starburst (Earth Pony) is a Creamy/Bleach White, While Prince Cos Nomi* (Alicorn Extraterrestrial Pony) is Chalk/Pearl white.
MLP belongs to Hasbro & Klaus Nomi belongs to Himself.
* Yes, I Finally Gave The Alicorn Nomi Pony a Name. The First part of His Pony Name "Cos" is Short for "Cosmos" or "Cosmic" Which while it Means "Order", "Harmony" or "Balance" in English. The Word Has been used in Discribing anything related to outer space or something magical. (Plus It was the only Thing that came close to sounding like "Klaus" without having to break the Outer Space theme.)

I also Learned some interesting Japanese Translations of the Word Nomi on Here. [link] [link][link][link][link]
so For the Sake of Whom I'm Hommaging with This OC, I am Leaving the Nomi Name alone.
As with Celestia, Luna, Candance & Chrysalis. Omni Starburst in His True Alien Pony Form of Prince Cos Nomi is of Royal Blood.
As for Why Someone of Royal blood Who Obviously has a Great Purpose Like Celestia & Luna But is Now in Disguse as an Earth Pony with a Talent & Desire for Singing. Well.....
