Check Palette CVD Safety — is_cvd

Quick check if a palette's worst-case minimum inter-color distance under simulated common CVD conditions meets a specified threshold.

Usage

is_cvd_safe(colors, min_cvd_distance = NULL, ...)

Arguments

colors: Character vector of hex colors or an OKLAB matrix.
min_cvd_distance: Numeric. The minimum acceptable perceptual distance (in OK LAB space) that any two colors in the palette should maintain under simulated deuteranopia, protanopia, and tritanopia. Defaults to the package-wide distinctness threshold (0.08). Recall JND is ~0.02.
...: Additional arguments reserved for future use.

Value

Logical. TRUE if the palette's worst_case_min_distance from evaluate_palette() is greater than or equal to min_cvd_distance, FALSE otherwise. Returns TRUE if palette has fewer than 2 colors.
