Okay, sectoral eyes JUST came out. And Xylax said he wouldn't be opposed to more tricolor eyes, so.. I immediately wanted to propose some ideas for that.

Explaination:
Basically, you need to first breed A eyes to B eyes to get AB sectoral. Then, you need to breed AB sectoral to C eyes and only then can you acquire ABC tricolor eyes. That makes for super rare, beautiful eyes.

Suggestion #1: Sectoral Jet + White and "Monochrome" AKA Jet, White, & Silver


Suggestion #2: Sectoral Amber + Yellow and "Fire" AKA Yellow, Amber, & Crimson


Suggestion #3: Sectoral Yellow + Sapphire and "Paint" AKA Yellow, Sapphire, & Pink


Suggestion #4: Sectoral White + Sapphire and "Blizzard" AKA White, Sapphire, & Ice

Suggested by Rosalie Hale (#54773)!

Suggestion #5: Central Yellow to Blue and "Sunrise" AKA Yellow, Blue, & Lavender

Suggested by Jelly[Satan]Property Of HL (#107370)!

Suggestion #6: (Already in-game) Sectoral Yellow + Green and "Flora" AKA Yellow, Green, and Brown

Suggested by Chianti [>Menhit<] (#33177)!

The shapes and arrangements are totally arbitrary and Xylax can rearrange them however he likes.
Critique and praise welcome! :D I'd also love more suggestions because I LOVE this idea.
