title: plotly - where can I find the default color palette used in plotly package
body: <p>I am primarily using the plotly package with r to plot my results. I would like to define the colors I use in my presentation document (tables, headings etc.) based on the default colors used in plotly. e.g. the colors used to fill the bars in a bar chart or the parts of a pie chart. Is there a way to find out the rgb or hex values?</p>
  
  <p>see the example here:
  <a href="https://plot.ly/r/pie-charts/" rel="noreferrer">https://plot.ly/r/pie-charts/</a></p>
  
  <p>I am looking for the rgb/hex values of the orange and the deep blue in the first pie chart.</p>
