DMC 806 — Dark Peacock Blue

The peacock is one of nature's most extravagant color achievements — the iridescent, jewel-like blue-green of its feathers has inspired artists, dyers, and designers across every medium for millennia. The "peacock blue" in the thread world isn't trying to fully capture that iridescence, which requires light and structure rather than pigment alone, but it does capture the specific hue: a rich, saturated blue-green that sits firmly between blue and teal with enough green to be clearly distinct from pure blue.

Where Blue Meets Teal

Color terminology around blue-green is inconsistently applied — teal, peacock blue, and turquoise overlap confusingly in casual use. DMC's nomenclature helps: "peacock blue" specifically designates the slightly blue-dominant side of the blue-green spectrum, as opposed to "peacock green" which would lean more green. DMC 806 Dark Peacock Blue sits at the deep, saturated end of this blue-green zone — its hex value reveals a color that reads as blue-dominant teal, not quite at either the pure blue or pure green pole but clearly anchored closer to blue.

This makes 806 a distinctive color that doesn't read quite like any other common thread color: it's not blue enough to be just blue, not green enough to be just green, not pale enough to be a pastel, not dark enough to be truly deep. This in-between identity makes it unusually recognizable in finished work — pieces featuring peacock blue in their palette have a distinctly different quality from those that use only blues or only teals.

Peacock Feathers and Exotic Birds

For cross-stitch patterns featuring peacocks — one of the most popular exotic bird subjects in the craft — the peacock blue family is obviously essential. DMC 806 as the dark value, paired with DMC 807 (Peacock Blue) for the mid-tone, creates the deep, richly saturated body feather color of the peacock's neck and breast. The "eye" of the tail feather typically requires this family alongside DMC 825 (Dark Blue) and DMC 991 (Dark Aquamarine) for the iridescent-looking eye-spot effects.

Kingfisher birds use the peacock blue family for their distinctive wing and back coloration — particularly the European kingfisher, whose back appears as an almost impossibly bright blue-green that falls in this exact range. Peacock-bass fish, blue-green scarab beetles, and certain parrot species in the turquoise-blue range also use 806 as their primary color fill.

Tropical and Coastal Design

Peacock blue is immediately associated with tropical environments — the color of water over a coral reef in bright sun, the color of certain tropical parakeets and lorikeets, the color of turquoise jewelry associated with southwestern American and Mediterranean cultures. Cross-stitch designs with tropical themes — beach scenes, ocean designs, tropical bird motifs — use 806 for the deepest, most saturated water or feather areas.

In mermaid and fantasy ocean designs, 806 and 807 together often form the primary palette for tail scales and underwater elements. The jewel-like quality of saturated peacock blue in thread reads exceptionally well for fantasy scales, where the slightly iridescent appearance of the thread under light mimics the effect of scaled skin.

Art Nouveau and Decorative Design

The Art Nouveau movement was fascinated by peacocks — the feathers appeared in Tiffany glass, Mucha illustrations, and decorative metalwork extensively. Art Nouveau-inspired cross-stitch patterns therefore reach for the peacock blue family regularly, and 806 provides the authentic, period-appropriate depth of color that these designs require. Paired with DMC 550 (Very Dark Violet) and DMC 783 (Medium Topaz), 806 creates the rich jewel-tone palette characteristic of Art Nouveau decorative art.
