I'm a big fan of how Koyori's mama draws hair, especially in this picture. It has this sheen to it, like mother of pearl. The nuance it adds to her hair colour just makes her even more beautiful.
You can see the same effect on the frills of her clothes, where it emphasises the softness of the folds, and conveys the luxurious feel of the fabric. Pic related, look how soft her chest looks, the tasteful way her top hangs loosely over her breasts.
