Spectroscopic Color Data for Common Dyes with sRGB Gamut Analysis

A dataset from 2026 by Calum Fyfe investigating the limitations of 8-bit sRGB color encoding for chemical analysis. It contains spectroscopic color measurements for a series of common dyes and simulated time-series data showing how gamut clipping can distort chemical monitoring. The dataset is 278.5 MB and shared under a CC-BY-4.0 license.

Use Cases

• Benchmarking color fidelity in camera-based chemical analysis based on spectroscopic dye data.
• Developing computer vision methods resilient to sRGB gamut clipping based on simulated time-series data.
• Studying the impact of color digitization on the interpretation of kinetic phenomena in chemical reactions.

Strengths

• Dataset size is 278.5 MB, indicating substantial content.
• License is CC-BY-4.0, permitting broad reuse with attribution.
• Focus on a specific, unaddressed technical issue (sRGB gamut limitations) in chemical analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
