DMC 453 to Cosmo: Thread Conversion

Cosmo 157 is a close match that may read slightly less pink than the DMC original. For most general uses of Light Shell Gray — background fills, pale accent stitching, lace textures — the difference is imperceptible. For designs specifically exploiting the rose-warm character of the shell gray family (portrait highlights, romantic wedding palettes), the close rating warrants a direct comparison test before using Cosmo 157 as the main highlight value in a three-step shell gray sequence.
