title: Multiple colors in Python
body: <p>I am plotting a dataframe with 100+ columns and I stacked all of them for each index value, the plot is below:
  <img src="https://i.stack.imgur.com/ArmCv.png" alt="enter image description here"></p>
  
  <p>However I wanted the color to be in a shading way, or at least the person can see the trend (from col1 to col100) so that it is clearer and I dont need those super long legends.</p>
  
  <p>Looking forward to any advice!</p>
