Choosing your customised calendar colours
Know your website colour scheme
In the example below, the colour scheme of the main website is teal and white. This colour scheme has been incorporated into the calendar design.
The booked dates are pale grey - it's not drawing attention to those dates but you can clearly see they are not available.
What to avoid doing when creating your calendars
Avoid using too many colours. The concept is to ensure your available days are the most important area to draw attention to. See below a bad example of too many colours.
Here you can't clearly understand what dates are booked, what you can click etc.
