    library(plotly)
    library(dplyr)

p <- ggplot2::diamonds %>% count(cut, clarity) %>%
  plot_ly(x = ~cut, y = ~n, color = ~clarity) %>%
  layout(barmode = "stack")

colors argument of plot_ly takes a vector of length numbers of categories:

p <- ggplot2::diamonds %>% count(cut, clarity) %>%
   plot_ly(x = ~cut, y = ~n, color = ~clarity, colors = rainbow(10)) %>%
   layout(barmode = "stack") 
p
