Color code identifies a named shade; dye lot identifies a production batch. Compare actual strands in the intended light before mixing batches.

## Before you start

Keep the exact labels and make two comparable samples. Change one material property at a time and use the intended finishing method on both.

## Try this example

Label balls A1 and A2 with the same color code but different lots. Make a joined sample; inspect the transition after washing before allocating whole panels.

## Check your result

- Compare the dry samples for recovery, surface, drape and the property needed for the project. Record observations separately from label claims.
- A fiber name or category cannot predict every finished fabric. Construction, treatment, gauge and use all affect the result.
