Pastel hair hues are stunning, but we're far more fascinated by the moodier takes on colourful coifs. Emerald dye captured our hearts. Smoky lilac styles mesmerised us. And now, midnight-blue manes are inspiring us to take the plunge into rainbow hair. Depending on how a colourist translates the look into your hair, your locks can appear like anything from a stormy sea to a starry night sky.
The beauty of this colour trend is that you can customise it to perfectly flatter your skin tone, though the more black that is in the mix, the more complementary it is to all complexions. Cool-skinned gals might want to add a bit more blue-based purple for a sultry indigo shade, while those with warmer complexions could add a bit of yellow-based green to suit their olive undertones.
