Clear warm blue
A True Spring color
anchor color 10 of 10 in True Spring. Also called Warm Spring in other systems.

Clear warm blue is the True Spring blue: a clean mid-blue with a touch of green in it, the blue of a swimming pool rather than a sapphire. It is the color that replaces cobalt for a warm season, and the one most often bought in the wrong version because retail blue runs either cool or dusty.
Clear warm blue is an anchor color in True Spring. Nothing on the same side of the warm–cool line comes within twenty points of it; the nearest is Light warm periwinkle #A5B4E8 in Light Spring at 24. That makes it a clean test. If it suits you, you are in this palette.
At RGB 46, 155, 214 the blue leads, the green sits a good way behind it, and the red is low. The green being well above the red is what makes it warm. The blue leading clearly is what keeps it a blue rather than a turquoise. Pull the green down and it becomes a cobalt that belongs to a Winter; add grey and it becomes the dusty cornflower that belongs to Light Summer.
A True Spring wears it as a color that reads as color: a shirt, a dress, a knit, a swimsuit. It pairs with cream and camel as the frame, with warm navy for a tonal outfit, and with coral and golden yellow for the two-color pairings that look like summer. It sits well next to warm turquoise, which is the same color with the green pushed ahead.
Retailers call it blue, bright blue, sky blue, azure, cerulean, pool blue or turquoise blue, and the names are unreliable: most of what sells as bright blue is a cobalt and most of what sells as sky blue is a pale cool blue. Hold the garment against a white. Clear warm blue looks bright and faintly green. A cobalt looks purple at the edges and belongs to a Winter. A sky blue looks grey beside it and belongs to a Summer.
No neighboring palette is closer than seventeen points, which makes this one of the more distinctive blues in the system. True Summer's bluebell is seventeen points off and dusty; Light Summer's cool sky blue and dusty cornflower are eighteen points off and both greyer: on a True Spring they read flat, and on a Summer clear warm blue reads loud. True Spring's own warm periwinkle is twenty-two points off and carries violet, the blue to reach for when this one feels bright.

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.
Yes. Clear warm blue (#2E9BD6) is an anchor color in the True Spring 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.
This one, warm turquoise, warm periwinkle and warm navy. Clear warm blue is the mid-blue, a clean pool blue with a touch of green. Cobalt and sapphire are cool and belong to the Winters; sky blue and cornflower are dusty and belong to the Summers. The test is a white sheet of paper: clear warm blue shows a green edge, cobalt shows a purple one.
No. Cobalt is deeper and cool, with no green in it, and it belongs to the Winters. Clear warm blue is lighter and warm. On a True Spring, cobalt reads heavy and cold; on a Winter, clear warm blue reads a shade green. Retail sells both as bright blue, which is the problem.
For a True Spring: cream, camel, warm navy, coral, golden yellow, warm turquoise and warm bright green. Cream and camel is the safe frame. Avoid black, which makes it look cold, and cool grey, which makes it look dull.
Not well. Light Summer's cool sky blue is eighteen points off, cooler and greyer, and clear warm blue at full clarity is both too bright and too warm for the season. The Summer version does the same job at the right temperature.
