Arctic Fox Hair Colour Periwinkle 236mlWatch the clouds go by with hair the colour of the sky. Periwinkle is a dreamy pastel blue with lavender undertones that will turn out best on platinum hair, and generally wont take to hair any darker than a level 9. #AFProTip: Try adding a bit of Sterling to Periwinkle to create a light denim blue shade, or punch it up for a slightly more pigmented color with a little bit of Poseidon!
