Generate palette suitable for coloring a set

Takes a simple palette and expands / oscillates it for use with Mandelbrot sets.

mandelbrot_palette(palette, fold = TRUE, reps = 1L, in_set = "black")

Arguments

palette	vector of color hex strings (e.g. '#FFFFFF')
fold	wrap or fold the palette back on itself
reps	number of times to replicate the color vector
in_set	color for areas in the Mandelbrot set

Value

an extended color vector

Examples

view <- mandelbrot(xlim = c(-0.8438146, -0.8226294),
  ylim = c(0.1963144, 0.2174996), iter = 500)

# can be used to simply interpolate a color gradient
spectral <- RColorBrewer::brewer.pal(11, "Spectral")
cols <- mandelbrot_palette(spectral, fold = FALSE)
plot(view, col = cols, transform = "inv")

# simple palettes might need folds / reps to look good
blues <- RColorBrewer::brewer.pal(9, "Blues")
cols <- mandelbrot_palette(blues, in_set = "white",
  fold = TRUE, reps = 2)
plot(view, col = cols, transform = "log")
