Conversion Notes
Sullivans 45400 is rated close and covers the general dark pink-mauve territory of DMC 3803. Some stitchers note it can lack some of the gray undertone that gives 3803 its moody Victorian quality — the gray that desaturates the dark pink into something more complex and period-appropriate than a simply vivid dark pink — leaning instead toward a somewhat cleaner dark pink. Sullivans' characteristic sheen at this deep saturated value adds surface luminosity that can work in either direction: in Victorian floral designs and dark cabbage rose pieces where a jewel-like depth suits the aesthetic, the sheen enhances the richness. In designs where the dusty, matte quality of Victorian mauve is specifically the design's period character, the sheen is slightly mismatched with that intention. For projects where the gray-tinged sophistication and the matte quality of 3803 are both important, comparing the Sullivans thread against your fill colors under natural light before committing to large fills is worthwhile. Anchor 69's exact match is the more reliable option for period-critical work.

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 3803 and Sullivans 45400 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 3803 and Sullivans 45400: 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.
