pal.safe

Show a palette/colormap for black/white and colorblind safety

Description

A single palette/colormap is shown (1) without any modifications (2) in black-and-white as if photocopied (3) as seen by deutan color-blind (4) as seen by protan color-blind (5) as seen by tritan color-blind

Usage

pal.safe(pal, n = 100, main = NULL)

Arguments

`pal`	A palette function or a vector of colors.
`n`	The number of colors to display for palette functions.
`main`	Title to display at the top of the test image

Details

Rates of colorblindness in women are low, but in men the rates are around 3 to 7 percent, depending on the race.

What to look for:

1. Are colors still unique when viewed in less-than full color?

2. Is a sequential colormap still sequential?

Value

None.
