Deep teal is a dark blue-green that leans green. In the Dark Autumn palette it is the color that reads as a jewel without being cool, which is a rare combination. It sits almost exactly between a Summer teal, a Winter pine and a True Autumn teal, and that is the whole story of why it gets misfiled.

Where it sits

Dark Autumn palette

Deep teal is an anchor color in Dark Autumn. The nearest color on the same side of the warm–cool line is Warm teal #2E7A72, a True Autumn color, at a distance of 13: close enough to mistake for it on a hanger, far enough to tell apart on a person.

Teal belongs to more seasons than any other saturated color, because the hue sits on the line between blue and green and small shifts push it across temperature lines. The Dark Autumn version is dark, with the green slightly ahead of the blue, and with a touch of grey that keeps it from going electric. That last part is what separates it from a Winter teal.

On a Dark Autumn it does what a jewel tone does for a Winter. Worn alone it is the strongest color in the palette that is not a red. Worn with the browns, mahogany, espresso, dark chocolate, it stops the outfit from being a wall of earth. It is the one color here that a Dark Autumn can wear to look dressed rather than warm.

Retailers make blue-teal in quantity and green-teal rarely. Most of what is sold as teal in a given season is closer to peacock or petrol, both bluer than this. The green-leaning version comes and goes, and when it comes it sells out, because every season that can borrow it does.

Easily confused with

Three colors sit thirteen points from this one: True Summer's spruce, Deep Winter's pine green and True Autumn's warm teal. That is an unusually even spread. In practice the Winter and Summer versions read bluer and cooler, the True Autumn version reads lighter and greener. Deep teal is the darkest of the four and the only one with grey in it.

Questions

Is deep teal a Dark Autumn color?

Yes. Deep teal (#1F5C5C) is an anchor color in the Dark Autumn palette. No other palette on the same side of the warm–cool line has a color near it, which makes it a reliable test for the season.

Is deep teal blue or green?

Green, slightly. #1F5C5C has equal green and blue values, but the hue sits at 180 degrees, the border, and the darkness pushes perception toward green. Beside a true blue-teal it reads clearly green. Beside a forest green it reads blue.

Can a Deep Winter wear deep teal?

Yes, as a jewel tone. Deep Winter's own pine green is thirteen points away and bluer. On a Winter, this teal looks a touch soft; on a Dark Autumn it looks exactly right. Both can wear it.

Can a Soft Summer wear deep teal?

Only the greyest versions. Soft Summer's muted teal is eighteen points away and much lighter. The depth here is more than a Soft Summer's low contrast wants near the face.

Why is teal so hard to pin to one season?

Because the hue sits on the blue–green border, and temperature is decided by which side it falls on. A few points bluer and it is a Winter color. A few points greyer and it is a Summer color. Deep teal is the dark, slightly green, slightly grey version, which is Autumn's.
