Generate random colors for leaflet map

Question

I am struggling to find a way to randomly mix discrete colors for my leaflet map for a large number of observations. The problem is the following command put similar colors next to each other which makes it hard to distinguish on the map.

library(leaflet) 
previewColors(colorFactor("RdYlBu", domain = NULL), LETTERS[1:26])

Is there any way to mix colors in a way it becomes A,Z,B,Y and so on ...

library(leaflet)
