Diverging colour gradient (continous).

Diverging colour gradient (continous).

Usage
div_gradient_pal(low = mnsl("10B 4/6"), mid = mnsl("N 8/0"), high = mnsl("10R 4/6"), space = "Lab")
Arguments
low
colour for low end of gradient.
mid
colour for mid point
high
colour for high end of gradient.
space
colour space in which to calculate gradient. "Lab" usually best unless gradient goes through white.

Examples
x <- seq(-1, 1, length = 100)
r <- sqrt(outer(x^2, x^2, "+"))
image(r, col = div_gradient_pal()(seq(0, 1, length = 12)))
image(r, col = div_gradient_pal()(seq(0, 1, length = 30)))
image(r, col = div_gradient_pal()(seq(0, 1, length = 100)))

library(munsell)
image(r, col = div_gradient_pal(low =
mnsl(complement("10R 4/6", fix = TRUE)))(seq(0, 1, length = 100)))
