i voted teal but i'd go with turquoise or aqua too. based on wikipedia's definitions turquoise is closest.
My argument:
1) Miku's character item is a leek. Leeks are green.
2) Miku is known for yasai/vegetable juice. Which is green.
3) Miku's glow stick is green. Kaito's is blue (also, he has blue hair and therefore it means Miku can not also be blue.) < I know Len's is orange, he doesn't count.
1. miku's item is actually a spring onion, the vegetable is not related to or the same color as her hair, and the association was fanmade to begin with
2. again, not related to her hair, and a fanmade creation
3. i haven't seen the glowsticks irl but i feel like their color could spark a whole other argument tbh. i'd say they're cyan based on what i've seen
Of course she has green hair you guys! I have been coloring her hair as green for over 14 years!
that's very impressive considering that miku has been released for about *checks pocketwatch* 12.5 years lol
personally i don't like when people call her green or blue but if i think about it i'm not that picky when it comes to other in-between shades. like a yellow-green sort of deal? i see that and i'm like yeah that's green. so idk why i'm particular about blue-green. it is my favorite color tho. people making miku more green or more blue in their fanart doesn't bother me. artistic liberty babey
above all, of course it doesn't really matter. we all be perceiving things differently
