Thank you for the comment. This is an internal helper function. It’s supposed to be hidden in the tutorial. I updated now the tutorial to hide it. Please find below the R code in case you want it

show_pal <- function(col, name = NULL, border = "white",  ...){
  n <- length(col)
  plot(0, 0, type="n", xlim = c(0, 1), ylim = c(0, 1),
       axes = FALSE, xlab = "", ylab = "", main = name,...)
  rect(0:(n-1)/n, 0, 1:n/n, 1, col = col, border = border, lwd =8)
}

Change point color by a grouping variable, then set the color manually:


library(ggplot2)
ggplot(iris, aes(Sepal.Length, Petal.Width)) +
  geom_point(aes(color = Species)) + 
  scale_color_manual(values = c("lightgray", "darkgray", "black"))

My dataframe is given below, the colour of the points is in col column.

head(df)
x1 x2 z col
1 0.72 2757 86 #2DFE89
2 0.72 2757 86 #2DFE89
3 0.72 2757 86 #2DFE89
4 0.70 2757 82 #28FE97
5 0.86 2757 26 #007C7D
6 0.75 2757 79 #24FEA1
