title: Change Jupyter notebook tab-autocomplete font color in Jupyter Lab?
body: <p>I am working with Jupyter notebooks in a Jupyter Lab setting over which I have limited control. After a recent update, I noticed that the tooltip font color for tab-autocompletion is very difficult to read:</p>
  <p><a href="https://i.stack.imgur.com/rv8oW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/rv8oW.png" alt="Example of poor contrast in tooltip font color" /></a></p>
  <p>How can I change the font color to make it more legible?</p>
