title: How to change colours on Pandas plot.pie()
body: <p>I am struggling with colours on Pandas pie plot. A sample code will help to isolate my issue in the present contest.</p>
  
  <pre><code>import numpy as np
  import pandas as pd
  a = np.zeros(31)
  b = np.zeros(69) + 1
  A = np.concatenate(( a, b) )
  np.random.shuffle(A)
  pd.Series(A).value_counts().plot.pie( autopct = "%.2f%%" )
  plt.show()
  </code></pre>
  
  <p>As you can see here <a href="https://i.stack.imgur.com/3SSD4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3SSD4.png" alt="enter image description here"></a> </p>
  
  <p>the result is a pie plot with blue and green colours respectively. What I am looking for is something like </p>
  
  <pre><code>pd.Series(A).value_counts().plot.pie( autopct = "%.2f%%", colours = ['red', 'pink'] )
  </code></pre>
  
  <p>But it looks like there isn't anything so easy. Could you help me, please?</p>
