TheTrendSpotter: While nudes may be the first thing that comes to mind when you want something universal, why not think outside the box and opt for grey instead? It’s an excellent base color that complements a whole rainbow of other hues, yet it’s unique and appealing enough to hold it’s own. From simple stripes and glitter to confetti and not-quite-50 shades of grey, there’s plenty of styles and designs to excite and inspire you before your next salon visit.
