Conversion Notes
Sullivans 45099 is a close match for DMC 3683 Light Mauve. The characteristic Sullivans sheen is particularly worth noting at this lighter value — pale threads with added surface sheen can read as noticeably brighter and slightly more luminous than their matte equivalents, which changes how the highlight behaves in a shading sequence. If 45099 reads as brighter than intended in its highlight role, the gradient may appear to have an exaggerated jump between the second-lightest and lightest values. For pieces where consistent surface texture is important throughout — particularly if you're mixing Sullivans with matte DMC threads in adjacent shading areas — the slight sheen difference can create a subtle inconsistency under raking light or in photography. For single-brand projects using Sullivans throughout the full color palette, this isn't a consideration, and the color performs adequately in the light mauve territory for decorative and floral applications. A swatch comparison confirming the sheen reads acceptably in your specific design context is the most reliable approach before large fills.

Watch for

- ! Brand sheen, strand thickness, and project lighting can make DMC 3683 and Sullivans 45099 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 3683 and Sullivans 45099: 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.
