DMC 738 to Sullivans: Thread Conversion

Sullivans 45179 is a close match for DMC 738 Very Light Tan and performs well in most practical applications. The slight differences in tone that come with a close rather than exact rating are unlikely to be perceptible at typical viewing distances unless the thread is placed directly alongside the DMC original under close inspection. For designs where 738 functions as a mid-light or highlight tan in an animal coat or skin-tone sequence, the close match means 45179 reads in the correct warm-neutral pale zone even if the precise balance of pink-warmth versus golden-warmth differs slightly from the DMC original. The most critical test is placing Sullivans 45179 between your chosen equivalents for DMC 437 (or 436) and DMC 739 and evaluating whether it reads as a natural mid-light step maintaining the same temperature as its neighbors, or whether it shifts warm or cool at the 738 position and creates a visible break in the gradient. If the step reads even, the close match is working correctly in context. For background fills and sandy landscape tones where the primary requirement is a consistent pale warm tan over large areas, dye lot consistency matters at this pale value — purchase all needed skeins at the same time to prevent subtle variation between lots that would be more visible in flat-fill work than in shading sequences.
