title: Change markerfacecolor for some of the markers in Matplotlib
body: <p>I have a plot that shows markers in a circle. I want to be able to change the colour of 3 of them. I've tried using a variable for markerfacecolor as follows but that doesn't work:</p>
  
  <pre><code>    angle = 0.0
      colorR = 'red'
      angleUpdate = 2 * numpy.pi / (len(v.T))
      for i in range(len(v.T)):
          x = numpy.sin(angle)
          y = numpy.cos(angle)
          angle += angleUpdate
          if i &lt; 3:
              colorR = 'green'
          v[0, i] = x
          v[1, i] = y
      plt.plot(v[0], v[1], 'ko', markerfacecolor = colorR, markersize = 70, clip_on = False)
      plt.show()
  </code></pre>
  
  <p>Is there a way of doing this?</p>
