  direction = 1,
  option = "the_blue_lotus"
)

Arguments

n	The number of colors (\ge 1) to be in the palette.
alpha	The alpha transparency, a number in ⁠[0,1]⁠, see argument alpha in hsv.
begin	The (corrected) hue in ⁠[0,1]⁠ at which the color map begins.

# without extrapolation: 5 or fewer colors
n <- 5

tintin_clrs(n, option = "the_blue_lotus")

image(
  1:n, 1, as.matrix(1:n),
  col = tintin_clrs(n, option = "the_blue_lotus"),
  xlab = "Tintin darkblue n", ylab = "", xaxt = "n", yaxt = "n", bty = "n"
)

# with extrapolation: 6 or more colors
n <- 20
image(
  1:n, 1, as.matrix(1:n),
