vangogh_cvd_scores: CVD Accessibility Scores for Van Gogh Palettes

Description

Pre-computed CVD accessibility scores for all Van Gogh palettes. This data is generated by running check_all_vangogh_cvd() and is included for quick reference without requiring the colorspace package.

Usage

vangogh_cvd_scores

Format

A data frame with CVD accessibility metrics:

palette

Name of the Van Gogh palette

cvd_type

Type of colour vision deficiency

min_distance

Minimum CIELAB distance between colours (higher = more distinguishable)

accessibility

Rating: Poor, Fair, Good, or Excellent

overall_rating

Average accessibility across all CVD types

Details

Distance interpretation:

• < 10: Poor - colours may be indistinguishable

• 10-20: Fair - some difficulty distinguishing

• 20-40: Good - generally distinguishable

• > 40: Excellent - highly distinguishable

Examples

if (FALSE) {
# View CVD scores
data(vangogh_cvd_scores)

# Find most accessible palettes
palette_summary <- aggregate(
  min_distance ~ palette, 
  data = vangogh_cvd_scores, 
  FUN = mean
)
palette_summary[order(-palette_summary$min_distance), ]

# Filter by CVD type
deutan_scores <- vangogh_cvd_scores[
  vangogh_cvd_scores$cvd_type == "Deuteranopia (red-green)", 
]
deutan_scores[order(-deutan_scores$min_distance), ]
}
