Calculate contrasting font colors for Google Sheets with Google Apps Script

If you are playing around with Sheet colors with Apps Script, you sometimes find yourself with font colors that don’t go well with the background colors you’ve chosen. However, we can use Yiq values to decide whether the luminance of the background color would be best with a light or a dark foreground font color. Here’s a small Apps Script library to figure it out for you.

Nice little helper library from Bruce Mcpherson if you’ve like to automatically apply contrasting colours to Google Sheets ranges. The source post from Bruce provides the background to the YIQ colour system as well as how to use the library. Follow the source link for more details.
