Powder blue

Where it sits

Light Summer palette

Powder blue is an anchor color in Light Summer. The nearest color on the same side of the warm–cool line is Icy blue #D6E4F0, a True Winter color, at a distance of 13: close enough to mistake for it on a hanger, far enough to tell apart on a person.

Light Summer is the lightest of the cool seasons, and powder blue is its signature for a reason. It has the season's cool undertone, its low contrast, and its softness all at once. It can be worn as a whole garment near the face without washing the person out, which is not true of most pale colors on most people. On a Light Summer it looks like the color was chosen for them.

Where it stops working is at the two borders of the season. Toward the Winters, the same pale blue loses its grey and becomes icy blue, True Winter's version, thirteen points away and visibly colder. Toward the Springs, it picks up yellow and becomes a light warm periwinkle, which is eighteen points away and reads lilac-warm rather than blue-cool. Both look wrong on a Light Summer in different directions.

Powder blue is sold as baby blue, sky blue, pale blue, and sometimes chambray. None of those names mean anything in particular. The test is grey: a Light Summer powder blue should look like it has been very slightly dusted. If it looks crisp and clean, it is a Winter blue. If it looks like it is leaning toward lilac or toward turquoise, it is a Spring blue.

Easily confused with

True Winter's icy blue is the close one, thirteen points away and the same hue with the softness removed. The other cool neighbours are all Summers: Soft Summer's greyed aqua and dusty lavender, True Summer's cool grey, and the periwinkle the Summers share. None of these are mistakes, just different weights of the same idea. The one that is a mistake is Light Spring's light warm periwinkle, which is warm.

The nearest named colors in other seasons, by perceptual distance (ΔE in CIELAB; under 10 is hard to tell apart on a screen, over 25 is a different color).

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.
