The problem: color failures with no common thread
When several batches come out off-color, the cause is often a shared raw material lot. Finding it means matching color data, recipes and lots by hand.
Three batches miss their color target in the same week. Each looks like a one-off until someone lines up the spectrophotometer data, recipes and lot numbers and spots the shared colorant lot.
What this demo shows
- Start from the batch and its recipe.
- Bring in spectrophotometer data.
- Check color against the product spec with Delta E.
- Trace three off-color batches to one raw material lot.
Why it matters
Off-shade batches cost rework, delayed shipments and sometimes customer complaints. Delta E checked against the spec as the readings arrive catches them at QC.
Seeing every batch against the limit, with its lots attached, makes the common cause visible in one view instead of after a week of comparison.

Uncountable connects quality and R&D. In it, paint color is data you can check. A tinted satin enamel batch reaches thin down. Rosa uploads the spectrophotometer export and the reflectance curve lands on the sample. The same sample holds its color as a result with L star, A star, and B star values. Uncountable calculates delta E2000 between this batch and the color standard.
The spec sets a maximum delta E. This batch is off shade, so its value turns red. One chart puts every batch's delta E against the limit, so the off shade batches stand out. Filter to every batch past the limit from the target color. They all used the same colorant lot. See how Uncountable connects quality, R&D, and the product record.
