Conversion Notes

Sullivans 45123 is a close match for DMC 550. At this depth of pigmentation, quality differences between Sullivans and premium brands are less visible than at lighter values — the dark saturation masks minor coverage and twist variations that would be obvious in a medium or light thread. The violet character should be present, though at this extreme dark end it's worth checking the thread in raking light on white paper to confirm the purple quality reads through rather than absorbing into near-black. For budget-conscious purchases where 550 appears in smaller quantities as an outlining or accent color — backstitching the interior of dark purple floral elements, for example — Sullivans 45123 is a practical choice. For designs where Very Dark Violet carries significant fill area, such as large wisteria backgrounds or gothic-style full-coverage pieces, the exact-match brands (Anchor 101 or Madeira 0714) provide more predictable and consistent results across multiple skeins.

Decision guide

When to trust DMC 550 to Sullivans 45123

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 550 is unavailable and Sullivans 45123 is good enough after a stitched sample check.
  • + Shortlisting a Sullivans substitute before you buy skeins, especially if your project can tolerate small differences in sheen or dye lot.
  • + Comparing this Sullivans 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 550 and Sullivans 45123 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

  1. Compare DMC 550 and Sullivans 45123: lay the physical skeins together in daylight before you mix brands in the same stitched area.
  2. Test on your project fabric: stitch a small sample so fabric color and stitch density reveal whether the match still holds at full coverage.
  3. 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.
