title: Plotly Value error - Invalid property for colour
body: <p>I have been experiencing errors while generating charts using Plotly and it seems to be affecting most of the charts I try producing on it. The error also seems to be a duplicate across all the failures. I am using Jupyter notebook (Anaconda 3, Python 3.6).</p>
  
  <p>Code that fails to generate output is found below (but my data table and everything else is correct).</p>
  
  <p>** I am unsure if there's some problem with the Plotly library (I'm using Plotly's latest that I installed using "Pip install Plotly")</p>
