In fashion, colors that fall outside the white-black-brown family are sometimes called neutrals - a better term may be universal . These hues tend to work with all other colors without changing their impact.
It seems like a new "neutral" pops up every few years, but some current examples are navy, olive, and teal. Metallics are also often considered neutral.
Most people will have wardrobe staples in these colors - so it's a good idea to work them into your designs, whether you're making jewelry for yourself or selling your creations.
These universal colors suit just about everyone because the quality of the colors is a mix of a little bit of everything, according to an article on The Chic Fashionista website.
These colors are neither too dark nor light, warm nor cool, and not too overpowering. Who doesn't look good in teal? And olive can be mized effectively with everything from raspberry to navel and coral. Check out Heather Power's color inspiration article for some great ideas.
Gray can be a perfect companion to everything from lemon yellow to fire engine red, sea foam and violet.
