DMC 522 to Cosmo: Thread Conversion

Cosmo 896 is a close match that captures the value well but may not fully replicate the grey muting — the dusty quality that distinguishes 522 from cleaner, more vivid greens. For designs where fern green is one of many background colors, this difference is an acceptable trade-off. For projects where the 520/522/523/524 family carries the primary color story, test Cosmo 896 against the full gradient family before committing, since a slightly more vivid midpoint can disrupt the soft, unified character the sequence depends on.
