Floral Color Loci Spectral Data for Graph Theory Analysis of Color Diversity

A 2026 study by Peng Ren provides spectral data for 954 floral color loci from the Floral Reflectance Database (FReD). The dataset includes wavelength data, photoreceptor sensitivity data for Apis mellifera, and results from color diversity calculations using graph theory methods. It is accompanied by the original R Markdown code for reproducing the analysis.

Use Cases

• Applying graph theory to model color diversity based on spectral reflectance data.
• Comparing color perception models (e.g., receptor noise-limited vs. color hexagon) for biological signals.
• Reproducing computational analyses of floral color evolution using the provided R code and data.

Strengths

• Includes data for 954 distinct floral color loci, providing a substantial sample size.
• Contains the original executable R Markdown script (Code_P-MIS.Rmd) enabling full reproducibility.
• Provides comparative results from two different algorithms (max_ivs and approx_rga) for color diversity calculation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the primary data tables is unknown, which may limit suitability assessment.
• Data may reflect the taxonomic and geographic bias inherent to the source FReD database.
