Need advice on pixel art colors

[bluppo8]

I have no idea what blocks to use for this hair:

Spoiler:

Advice pls.

EDIT: I've decided on the least terrible looking color for Soga no Tojiko's hair. Now I just need advice on Toyosatomimi no Miko's hair.

Does sand/sandstone work?

I guess, but I need a block for every shade of color of her hair. I was thinking of using birch wood planks for the lightest or second lightest color.

quarts, sand, birch, brown wool?

[bluppo8]

That might actually work. I'll try it once I get to Miko's head.

EDIT: Done.
