Dusty blue

Where it sits

True Summer palette

Dusty blue is an anchor color in True Summer. Its closest relative outside the palette is Slate blue #6E7F94, a Soft Summer color, at a perceptual distance of 6. That is near enough for that season to wear it as a neutral, with the accents kept in its own palette.

The Summers own greyed blue the way the Autumns own brown. Dusty blue is the center of that family: not navy, not sky, not denim, but the blue of a chambray shirt that has been washed a hundred times. It is a near-neutral in the True Summer palette and pairs with everything else in it.

The test is the grey. Hold the garment beside a clear blue, a cobalt or a royal. If it looks soft and greyed by comparison, it is dusty blue. If it looks like a lighter version of the clear one, it is a Winter or Spring blue and will look loud on a Summer face.

On a True Summer this is a daily color: shirts, knits, trousers, a coat. It is forgiving, it photographs well, and it is sold under enough names that a shopper will find it in most seasons. Coastal blue, harbour, chambray, dusk and storm are the common ones.

Easily confused with

Slate blue, #6E7F94, is Soft Summer's version, six points away and a touch greyer. Light Summer's soft grey-blue is twelve off and lighter. Periwinkle and bluebell, both in the True Summer family, carry more violet. If a blue looks faintly purple beside this one, it is one of those.

A retailer's name for a color says nothing about its undertone. "Navy" at one shop is a True Winter color and at another a Spring one. The sampled dot on each card above is what we trust.
