DMC 964 to Cosmo: Thread Conversion

Cosmo 933 is close-rated for DMC 964. Slight differences in the blue-green balance from the DMC original have been noted, and at this pale value these subtle shifts are proportionally more visible than in deeper colors. For designs building a gradient with DMC 958 and 959 below, testing Cosmo 933 against those colors ensures the seagreen family's blue-green character reads consistently across the progression before committing to a full project substitution.
