Deciding Koa's Hair Color [Sketch Poll] (Patreon)

Guys, let us introduce Koa! The Syquanite main girl of the game!
But! We need your help to decide which color combination looks better on her:

Let me have some thoughts about each option:
1 - Blues, from dark to clear blue. Simple and effective.
2 - Nice and daring combination of colors for a tropical island girl.
3 - Beautiful combination of colors, but reminds me a little bit of the one used on Teigan.
4 - Similar to 2 but with less color variation that somehow gives her a nice "marine" touch. Not sure if some people could think they are related with Yalenites though (and no, they aren't).

You have attached the files in case you want to check them with detail.
In one week we'll know the final results :)
