Deep Violet / Plumbeous, Veronia Purple and Red Violet
Muted grey, a smoky rose and a dark grape: the effect is hushed, like an Art Deco hotel lobby after closing time. Deep Violet / Plumbeous supplies the cool stone, Veronia Purple the faded velvet, and Red Violet the shadow in the corners. A boutique hotel website or a vintage jewellery brand would wear it well, provided the text comes from a lighter fourth color, as contrast inside the trio stays low.
