Color-Coded Time Blocks

Color the background of entire days or time ranges with the colors option. You can specify backgrounds as exact dates, ranges or set up recurring rules. The recurring object works the same way as for the events. Optionally, you can specify a title as well, which will be displayed on the colored block.

Use the onPageLoading lifecycle event to color backgrounds runtime. You can learn about lifecycle events and places where to drop logic to customize the experience.
