Check Palette CVD Safety

Source: R/cvd_analysis.R
is_cvd_safe.Rd

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 = 0.08)

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. Default is 0.08. Recall JND is ~0.02.

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.
