Simulates protanopia, deuteranopia and tritanopia (Machado et al., 2009) and
measures the smallest CIELAB color difference (CIE76 dE) within the discrete
palette of n colors returned by portinari.pal(), for every n. A
discrete palette of n colors is colorblind-safe when all three
simulations keep that minimum at or above threshold.
Usage
portinari.cvd.check(palette = "cafe", threshold = 10)
Arguments
- palette
Name of the palette. See portinari.palettes().
- threshold
Minimum acceptable dE. Default 10.
Value
A data frame with one row per palette size n (from 2 up to the
palette length) and columns normal, protanopia, deuteranopia and
tritanopia (minimum pairwise dE in each condition) and
colorblind_safe.
