Textile Colorimetry & Dyebath Formulation Assistant
Convert spectral data into precise dye recipes and fastness predictions
What You Can Do
You can input spectral reflectance data, customer color swatches, or CIE Lab* values and receive detailed dye combination recipes scaled to production batch sizes. The skill calculates color differences (ΔE) against standards, predicts fastness performance across light, wash, and crocking exposure, flags metamerism risks, and identifies incompatible dye class combinations—all structured for immediate handoff to production teams.
Features
converts raw colorimetric data into actionable color specifications
compares customer samples against internal standards with pass/fail metrics
identifies compatible dye classes and weight percentages for target hue and saturation
estimates light, wash, and crocking fastness based on dye chemistry and fiber type
produces production-ready formulations with material weights, temperatures, and timing
alerts to potential color shifts under different light sources and dye interaction risks
exports color properties, fastness data, and batch notes for sales and quality assurance handoff
adjusts recommendations for cotton, polyester, wool, and blend substrates
