We love a timeless black feline flick of liquid eyeliner, oh yes we do. The new way to wear it: swap black for an intensely pigmented jewel tone and you’re instantly on-trend. In this How-To video, MECCA Makeup Artist Sally Axford creates an amethyst eye statement – and shows you exactly how to perfect the perfect line. "Amethyst is actually the perfect tone to compliment green or hazel eyes," she explains. For best effect, choose a shade that works well with your own eye colour; Sally suggests sapphire for brown eyes and garnet or a coppery bronze for blue eyes. Add a coloured mascara for maximum impact – and be prepared to be noticed.
