COLOURS by Gina Curated Colour is calibrated to be fully intermixable and includes a range of pure mixers to add concentrated tone to any shade, as well as a shade diluter to soften any tone or lighten any level. Curated Colour Naturals are cool leaning, rather than warm leaning, to help counteract natural warmth and give a true neutral, natural result on gray or natural hair. True neutral naturals, mix and match shades, adjust levels, dilute tones and invent your own colour, or use one of Gina's favorites, the choice is yours.
