To celebrate the 30th anniversary of their world-renowned nail brand and how nail polish has become a means of self-expression, OPI have created a short film to highlight their much-loved quirky-named nail shades. Instinct of Colour stars a rather talented young thoroughbred named Lady in Black, who, showcases four of OPI’s nail polishes on her hooves, whilst having a ballet, tap, modern and street-dance dance-off.
