For women with cool undertones, a plain blue shade will seem harsh against your skin. The best way to solve this is to add a tinge of violet hues to the mix. The simple addition of the subtle violet shade will deliver the warmth your pale skin needs.

6. Curly Hair + Bright Blue Underneath

Not everyone can pull off a bright blue hair color. But if you really want to make a fun, bold statement to your black hair, this is the color to go for.

Just a heads up, it works best with a cool complexion. If you have a warm skin tone, it’s best that you go for purplish- or greenish-blue shades.

7. Wavy Ends + Shades of Blue
