Data for: Online visual screening of glass-jar instant coffee packaging and colour variants

This dataset supports the manuscript “Online visual screening of glass-jar instant coffee packaging and colour variants.” Version v2.1 is a metadata, documentation, and reproducibility-package correction of v2.0. It replaces the two repository ZIP archives with corrected versions that remove obsolete manuscript-title wording, the superseded version-specific DOI, and legacy “controlled-colour” terminology, while retaining the same underlying study data and analytical results. Apart from documentation and variable-description corrections, the analytical worksheets contain no substantive data changes. The public reproducibility archive includes the complete executable Python verification workflow, environment and dependency information, SHA-256 audit manifests, and revision-time rerun documentation. The archived verification report records 607/607 checks passed under the locked Python 3.12.x environment, and all archived derived outputs used for the audit matched the retained references. The workbook contains de-identified respondent-level semantic and colour-rating matrices from 503 adults in China, aggregate sample summaries, measurement diagnostics, complete-package omnibus diagnostics, colour-variant results, forced-choice summaries, anonymised raw AHP pairwise matrix values and expert-priority results from 20 experts, sensitivity diagnostics, and provenance records. Respondent IDs are pseudonymous; IP addresses, exact timestamps, demographic microdata and direct identifiers are not shared. Privacy-withheld membership variables prevent reconstruction of the two consumer sensitivity subsets from the public workbook alone. Commercial complete-package stimulus images are not publicly redistributed because they contain third-party brand imagery and are subject to copyright restrictions; non-branded descriptions and schematic documentation are provided instead.
