Colors in plotly bar graph R

Question

When using a variable for color in a plotly bar graph. How do you change the default color scheme?

    library(plotly)
    library(dplyr)

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

p

   plot_ly(x = ~cut, y = ~n, color = ~clarity, colors = rainbow(10)) %>%
   layout(barmode = "stack") 
p
