title: How to change the color of a treemap in r
body: <p>I would like to know how to change the color for this treemap to "#453781FF". I have already tried with diferent ways, this is best posible solution, yet it is not the expected results, as you can see the color of this image is pink.</p>
  
  <pre><code>library(readr)
  library(ggplot2)
  library(treemapify)
  
  url_t = "https://raw.githubusercontent.com/frm1789/landslide-ea/master/df_treemap.csv"
  df_t = read_csv(url_t)
  
  ggplot2::ggplot(df_t, ggplot2::aes(area = n, label = country, fill = 
  "#453781FF")) +
  #geom_treemap(color = "red") +
  geom_treemap(aes(alpha = v_alpha)) +
  geom_treemap_text(fontface = "italic", colour = "white", place = 
  "centre",
                  grow = TRUE)
  </code></pre>
