Change color of bar plots

I have a plot:

p <- plot_ly(
  x = c(data$sum),
  y = c(data$candidate),
  name = "Trump v Clinton",
  type = "bar"
)

Candidate is realDonaldTrump and HilaryClinton while sum is 10000 and 5000.

Is it possible to set the colour for the bar of each candidate? I.e. Trump be red and Hilary blue.

Looking for something like this?:

library(plotly)

data<-data.frame(sum=c(10000, 5000), candidate=c("DonaldTrump", "HilaryClinton"))
data$color<-c("red", "blue")

p <- plot_ly(
  y = data$sum,
  x = data$candidate,
  color = I(data$color),
  type = "bar"
)
p<-layout(p, title = "Trump vs Clinton")
print(p)

It plot as a vertical barplot, I needed to swap the values for the x and y axis.

This should also work:

library(plotly)
data.frame(sum=c(10000, 5000), candidate=c("DonaldTrump", "HilaryClinton")) %>% 
  plot_ly(x = candidate, y = sum, type = "bar", color = candidate)

enter image description here
