DMC 934 to Cosmo: Thread Conversion

Cosmo 923 is rated close for DMC 934. At this extreme dark value, slight differences in the olive-avocado character are relatively less perceptible than they would be in a mid-tone color — very dark threads read as dark green regardless of subtle undertone variation at normal viewing distance. For botanical shadow work and forest designs where the specific avocado quality of 934 is important, testing remains advisable, but the practical risk of substitution is lower here than for lighter shades.
