Zed and the Red Cape

So I recently watched the the animated short "Death Mark" ( which was great Riot, keep it up) and all of the sudden a voice popped up in my head, saying something is off. At the end of the video we see Zed standing over his new victims, his red cape moving in the wind, which got me thinking:" Why is Zed, a well trained ninja, wears something so colorful? the red parts in his armor are dark enough to blend in shadows but the cape? doesn't make any sense" And then it hit me. As we know from the lore, Zed,Shen and their master went out to find and stop the Golden Demon (Jhin which I love give him more skins and buffs) and as the hunt went on, they all lost something, Zed began to fail and dubt his studies,Shen lost his happy behavior and The Master lost his most known feature.... his Red Hair. MY THEORY: Zed either wants to honor his Master by this feature, or he wants to show the world that he can become better then his Master, wearing his signature as a sign of supremacy or even both. please let me know if it's a known fact or if I really found out something and if I did, what do you think? Is it honoring or shaming Zed's Master?
