DMC 824 to Sullivans: Thread Conversion

Sullivans 45225 is a close match for DMC 824 Very Dark Blue. The close rating in deep blues like this typically reflects a minor undertone variation that's less critical at this dark value than it would be at a mid-range value. Coverage is solid at standard Aida counts, and the color reads as dark blue in finished work without looking obviously different from DMC 824. For large ocean or sky fills, buying a consistent lot from the same source reduces any visible dye lot variation in Sullivans' product. One practical consideration for designs using 824 as the dark anchor of a blue gradient: if you're substituting Sullivans 45225 for DMC 824 at the bottom of the gradient, using Sullivans equivalents for the lighter blues in the same progression maintains internal consistency better than mixing Sullivans at the dark end with DMC at the lighter steps, where any undertone difference would become visible at the transition between brands.
