DMC 156 — Medium Light Blue Violet

The Periwinkle Problem, Solved

Every stitcher who has tried to render periwinkle flowers, morning glories, or cornflowers in cross stitch has faced the same frustrating question: is this color blue or purple? Pattern charts often list these flowers as blue, but your eye sees purple. Color cards say violet, but the thread in your hand looks lavender-blue. DMC 156 Medium Light Blue Violet sits precisely at the resolution point of this argument. At #A3AED1, it is a medium-light, slightly grayed blue-violet that reads as periwinkle — not firmly blue, not firmly purple, but that particular color where the two families merge into something distinct.

The grayed quality is important. Pure blue-violet at this value would be vivid and assertive, but 156 carries enough gray to soften it into something gentler, more approachable. It is the color of distance — far-away mountains at the edge of a landscape, the middle value of a watercolor wash, the sky reflected in still water after sunset. That atmospheric quality makes 156 enormously useful for background work, sky areas, water surfaces, and any situation where you need color that sets a mood without dominating the composition.

Photographing the Unphotographable

Let's address something practical that affects every stitcher who posts their work online: DMC 156 is one of the hardest colors in the range to photograph accurately. The blue-violet range sits at a point in the visible spectrum where digital camera sensors struggle, and 156's relatively light value compounds the problem. Photographs tend to push it either toward blue (losing the purple character) or toward a more saturated violet (losing the grayish softness that defines the thread in person). Fluorescent lighting makes it look distinctly blue. Incandescent light pushes it warm and almost lavender.

If you need accurate photos of a finished piece using 156, shoot in natural diffused daylight — an overcast day or a north-facing window provides the most neutral light. Avoid auto white balance, which will typically correct the blue-violet cast right out of the image. If your camera allows manual white balance, setting it for daylight will give the most faithful rendering.

Using 156 in Gradient Work and Ombre Effects

DMC 156 is the third step in the four-shade blue-violet gradient: DMC 3746 (Dark Blue Violet) at the deep end, DMC 155 (Medium Blue Violet) in the middle, 156 as the light-medium step, and DMC 3747 (Very Light Blue Violet) at the lightest end. This gradient is one of DMC's most elegant sequences — each step is distinct but the transitions feel natural, with no awkward jumps in value or hue.

For ombre effects, this gradient works beautifully across a band sampler or geometric border pattern. Start each row or section with 3746 at the top, step to 155, then 156, and finish with 3747. The cool temperature remains consistent throughout, so the eye reads the gradient as a single color in shifting light rather than as four different colors. This is one of the advantages of working within a well-designed color family — the undertone consistency makes gradients look intentional and sophisticated rather than patchy.

In larger landscape pieces, 156 excels as a distance color. Distant mountains, far-off treelines, and deep background elements in landscape painting often shift toward blue-violet as atmospheric haze desaturates and cools the colors. Stitching distant elements in 156 creates convincing aerial perspective — the visual phenomenon where distant objects appear lighter, bluer, and less distinct than near objects. Pair with closer foreground elements in warmer, more saturated colors and the sense of depth becomes remarkably convincing for a medium built on tiny X-shaped marks.
