Is there a way to color the background say 10 days before earnings up until earnings and then a different color 10 days after earnings.
Here you go. Bring up the settings window to change the number of days before / after earnings, whether to show the vertical lines and / or fill in the background colors, and to change the default colors for each component.

Hi Bob,
Can upcoming earnings date be plotted by this script?
Yes, just extend the time-axis to the right far enough to include future earnings dates.

This code is designed to work on a daily time frame.
