DMC 891 to Cosmo: Thread Conversion

Cosmo 2505 is a close match for DMC 891 Dark Carnation. Cosmo's silkier thread finish at this high saturation level can amplify minor hue differences — the thread's surface interacts with light differently, potentially making the Cosmo version appear marginally more vivid or with a slightly shifted warm-pink character. For floral designs where the exact deep vivid pink of 891 is central to the gradient, testing Cosmo 2505 in your fabric and lighting confirms whether the family relationships hold. For standalone bold pink use, Cosmo 2505 performs adequately.
