While Cruella de Vil solidified the trend with her iconic black and white locks, colorists on Instagram have given split hair color a technicolor upgrade. For the more subdued client, a pairing of rich brunette and pale, buttery blonde makes for a refined combination. Coupling the client’s natural hue with a pop of bright, unexpected color helps ease into the bold style. And then, of course, there are those who go all in. From cotton candy pink and blue to intoxicating scarlet and spicy coral, each plucky coupling makes this trend even more alluring.
