You can also use something like this to retrieve the colours used in your plot:

return.plot_ly.ColorsUsed <- function( plotlyObject ) {

      explorePlot = plotly_json(plotlyObject)
      explorePlot = jsonlite::fromJSON(explorePlot$x$data)

      # Extract colors, names and fillcolors
      colors = explorePlot$data$marker$color
      names = explorePlot$data$name
      fillcolors = explorePlot$data$marker$fillcolor



      # Returns a list with the names, colors and fillcolors used in the plot
      toReturn = list( "names" = names,
                       "colors" = colors,
                       "fillcolors" = fillcolors )

      return(toReturn)


} # End FUnction return.plot_ly.ColorsUsed
