We naturally stick to what we like --
Even when we don't mean to, you would probably have a collection of same wig colors with varying styles.
Naturally, we have our 'identity' and we know what naturally looks nice for ourselves. (So don't ever lose this to critics or even friends giving you their opinions -- remember! They're opinions, take them at face value. It's up to you how you want to do this hobby)
But again, the opposite doesn't hold true -- but then again am pretty sure there will always be that ONE color you like wearing the most. As for me, it's blonde, green (mostly Miku and CC) and silver. It was a hard battle between the blondes: Len versions, Saber versions, Krista, Mio and a whole bunch of others but in the end Saber Alter won out the spot.
I'd love to see your Wig Color Meme! :)
I can give you a copy of the template I used if you wish (Or I'll update this soon with a download for it)
