title: How to change colour of points in ggplot
body: <p>Using <code>library(tidyverse)</code>, fix this code by making the point blue instead of red:</p>
  <pre><code>ggplot(data = mpg) + geom_point(mapping = aes(x = displ, y = hwy, colour = &quot;blue&quot;))
  </code></pre>
  <p>Not sure where where to input the code to change it to blue instead of red, can anyone explain why it is default red and what the code would look like to change the colour?</p>
