title: Why is pyplot's histogram giving two different colors?
body: <p>edit: What I am trying to reproduce is this histogram:<a href="https://i.stack.imgur.com/KTmF7.png" rel="nofollow noreferrer">enter image description here</a>. </p>
  
  <p>So I'm plotting a pretty large dataset of two different sets of times. But I'm getting a histogram with blue and orange bars. </p>

  <p>Everywhere else I looked to see if someone has asked/answered this question yields results for wanting to change the colors. However, every other time I've used hist, I just get blue bars as default. </p>
  
  <p>Here is my code:</p>
  
  <pre><code>filename='24.txt'
  data=np.genfromtxt(filename, usecols=(0,3), skip_header=4)
  bins=15    
  entries, edges, _ = plt.hist(data,bins,)
  </code></pre>
