anchor color 8 of 10 in Deep Winter. Also called Dark Winter in other systems.

Cool blue-red is red with no orange in it. It is the Deep Winter red, the one that makes the face look awake rather than flushed. Warmer reds, tomato and brick and rust, belong to the Springs and Autumns. This one is blood, not fire.
Cool blue-red is an anchor color in Deep Winter. Nothing on the same side of the warm–cool line comes within twenty points of it; the nearest is Magenta #C2185B in True Winter at 20. That makes it a clean test. If it suits you, you are in this palette.
Retailers make far more warm red than cool red, and most of them call all of it red. The test is the undertone. Hold the garment next to something orange. If the red looks pink by comparison, it is cool and probably yours. If it looks like a darker orange, it is warm and probably not.
On a Deep Winter this red does what black does, which is sharpen the face, and it does it with more presence. It is the color for the one piece that has to carry an outfit, a coat or a dress or a knit worn alone, with everything else in black, charcoal or blackened navy. It does not need a second color. It does not want one.
The hard part is finding it saturated and cool at the same time. A lot of blue-based red on the market is dialed down into cranberry or burgundy. Those are good Deep Winter colors, but they are different ones, and they sit elsewhere in this palette. #B00030 is the full-strength version.
The nearest colors in other palettes are True Winter's magenta and the shared true red, both roughly twenty points off. True red is the one people reach for by mistake. It has a drop of warmth that blue-red does not, which is why a True Winter can wear both and a Deep Winter is better in this one.

Retailers almost never use the palette name. These are the color names on the in-stock pieces that sample within a close match of #B00030 today, so they are the words to search for.
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. Cool blue-red (#B00030) is an anchor color in the Deep Winter 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.
The undertone. A cool red leans toward blue and pink; a warm red leans toward orange. Put the garment beside anything orange: a cool red turns pinkish by comparison, a warm red reads as a dark orange.
Yes. It sits about twenty points from True Winter's own true red and magenta, and all three are blue-based. On a True Winter it reads a shade deep; on a Deep Winter it is the center of the palette.
No. Burgundy and cranberry are this red with the light taken out, and they are separate colors in the Deep Winter palette. Blue-red is the saturated version, the one that holds its own against black.
A blue-based red with no coral in it. Shade names vary by brand and the names lie, so test on skin against the garment in daylight. If the lip looks pink next to the fabric, it is right.
