Conversion Notes
Cosmo 376 is a close match for DMC 806 Dark Peacock Blue. Saturated teal-blues are one of the more variable color zones across brands because the blue-green balance point is defined relative to the full spectrum, and small formulation differences can pull the color noticeably in a more blue or more green direction without the change looking proportionally large in the skein. For peacock designs where 806 and 807 work together as the dark and light peacock values, checking that Cosmo 376 reads consistently with your mid-value Cosmo peacock thread — Cosmo 453 if using Cosmo for 807 as well — in natural light is important for maintaining the hue family coherence across the gradient. A close substitute at 806’s position that reads greener than the DMC original will make the dark peacock position look like a different color family from the lighter positions if those lighter positions use DMC or Anchor exactly. Cosmo’s slight silky finish can give deep saturated teals a particularly vivid, jewel-like quality that may enhance the visual richness of peacock and Art Nouveau designs in display conditions. For standalone dark peacock accent use without adjacent gradient steps to maintain family coherence, Cosmo 376 is workable without extensive testing.

How We Validate This Match
This Cosmo page is meant to help you shortlist a replacement quickly, then verify the physical skein before you mix brands in the same stitched area.

Decision guide
When to trust DMC 806 to Cosmo 376
This page is strongest as a decision aid, not as a guarantee that two branded skeins will vanish into each other without testing.
Best for
- + Replacing missing floss when DMC 806 is unavailable and Cosmo 376 is good enough after a stitched sample check.
- + Shortlisting a Cosmo substitute before you buy skeins, especially if your project can tolerate small differences in sheen or dye lot.
- + Comparing this Cosmo candidate against the other conversions and nearby DMC shades linked from the page before you commit to a full swap.
Watch for
- ! Close matches are not safe to assume interchangeable in focal areas without a physical test on your fabric.
- ! Brand sheen, strand thickness, and project lighting can make DMC 806 and Cosmo 376 look further apart than the stored match rating suggests.
- ! If the design depends on smooth gradients or skin-tone transitions, compare this swap against the neighboring DMC shades before you substitute a large block.
Before you commit
- Compare DMC 806 and Cosmo 376: lay the physical skeins together in daylight before you mix brands in the same stitched area.
- Test on your project fabric: stitch a small sample so fabric color and stitch density reveal whether the match still holds at full coverage.
- Keep a fallback ready: if the swap feels off, use the linked related DMC shades or another brand conversion instead of forcing the closest stored match.
