DMC 797 to J&P Coats: Thread Conversion

J&P Coats 7023 is a close match for DMC 797 Royal Blue. For large fill applications — idealized sky backgrounds, graphic geometric fills, extensive flag motifs, bold blackwork designs in royal blue — sourcing a consistent dye lot of J&P Coats 7023 is especially important, since saturated blues in large fill areas make any subtle lot-to-lot variation more apparent than it would be in smaller accent quantities. The bold, assertive quality of royal blue is more about saturation and value than about subtle hue calibration, so the close rating is less concerning for 797 than it would be for a muted or pale color. The essential test is whether J&P Coats 7023 reads with the same visual weight and graphic presence as DMC 797 — if the substitute reads as a slightly lighter, grayer, or less saturated blue, it will lose the authority that makes royal blue so effective in ceremonial, patriotic, and graphic-design-inspired cross-stitch. For designs where 797 works in a classic gold-and-blue heraldic pairing, the saturation of the blue is what creates the maximum complementary contrast, and a less saturated close substitute will reduce the visual impact of that pairing. For standalone bold blue accent use in modest quantities, J&P Coats 7023 provides a practical working substitute in most conditions.
