DMC 598 to Sullivans: Thread Conversion

Sullivans 45134 lands as a close match in the light turquoise zone. The practical test for any Light Turquoise substitute is to hold it equidistant from a true pale blue and a true pale green — if it reads as balanced between both with a slight lean toward blue, you’re in the right territory; if it strongly favors one side, you’ve drifted into adjacent territory. The swimming-pool warmth of 598 comes from the green component, and any substitute should feel noticeably warmer than a conventional sky blue. For coastal, summer, and pool-themed designs where any warm light blue-green reads correctly, Sullivans 45134 is a functional choice. For precise gradient work alongside DMC 597, compare in daylight before stitching.
