Hilary Duff's been experimenting with her hair color quite a bit over the past few years, rocking quite a few pastel shades along the way. This rock 'n' roll pale pink bob was a great look for her — wouldn't it be cool to see her wearing the shade on her TV show "Younger"?

This look happily marries two of today's coolest hair trends: A wavy undone lob and rose gold strands. Definitely an all-around win.

Don't you love the way this 'do fades from a natural brown to a deep purple to a rose gold, all the way down to a pale peach? The overall effect is truly stunning.

This style seamlessly blends Old Hollywood glam with a futuristic fairy princess twist. Honestly, the long pinky-lilac waves look like something Princess Bubblegum from "Adventure Time" could really rock.

Going for rose gold tones doesn't necessarily mean you have to bleach your entire mane platinum — if you go for an ombre bayalage look like this with a dip-dye effect, it means you'll only have to lighten the lower half of your hair.
