Why Does Fabric Color Differ Between Orders? Understanding Dye Lot
One of the most frustrating surprises when ordering more fabric for an existing project: the same color name, but a noticeable slight difference when placed next to the original quantity. There's a clear explanation for this.
What is dye lot variation?
Every time fabric is dyed, a separate dye batch (lot) is produced. Even using the exact same color recipe, subtle factors (dyeing temperature, soak time, even the raw yarn batch itself) can produce a very slight difference — sometimes invisible to the eye, sometimes noticeable in direct comparison.
When does this become noticeable?
- Ordering additional quantity for an existing project some time after the first order.
- Using two pieces from different sources for the supposedly same color.
- In spaces where pieces sit side by side (two adjacent sofas, curtains in two connected rooms).
How to avoid this problem?
- Buy the project's full quantity in one go whenever possible, even if you don't need it all immediately.
- If you need an additional order later, request it from the same specific supplier and tell them it's an extension of a previous order — some suppliers keep batch records.
- Request a sample of the new batch and compare it directly to the original piece before the full order.
Can a 100% match be guaranteed?
It's hard to guarantee a perfect match across completely different batches, but working with a supplier that cares about quality control reduces the difference to something practically unnoticeable in most cases.
