DMC 548 to Sullivans: Thread Conversion

Sullivans 45206 is a close match for DMC 548. For the rim-highlight application — a single row of 548 stitches at the edge of a blue fill to suggest reflected light — any pale blue-white in the right approximate zone performs the role effectively. The ultra-pale value means the eye processes the color more as tonal modulation than as a specific hue, making this one of the color range positions where the substitution gap between brands is smallest in practical terms. A reasonable economy choice for accent use.
