title: R ggplot2 theme_set colorblind or dichromat color?
body: <p>In R ggplot2 are you able to <code>theme_set(theme_grey() + "colorblind_function"</code> at the top of the code rather than adding <code>+ scale_color_colorblind()</code> to each plot?</p>
  
  <p>Some ggthemes I've used in the past:</p>
  
  <pre><code>show_col(colorblind_pal()(8))
  show_col(tableau_color_pal("colorblind10")(10))
  show_col(dichromat_pal("BluetoOrange.10")(10))
  </code></pre>
