Hi,

Odoo's Time Off module uses colors associated with work_entry_types to visually distinguish different types of work entries and time off requests. While you can assign a work_entry_type to public holidays, the calendar display doesn't automatically inherit the color from that work_entry_type. This means the color coding you see for mandatory days off won't directly apply to public holidays in the calendar.

To achieve a similar color-coding effect for public holidays, you'll likely need to customize Odoo. The most reliable method is to create a custom module that fetches the color from the related work_entry_type and modifies the calendar view to use that color for displaying public holidays. Odoo Studio might offer limited customization options, but it's unlikely to provide the necessary level of control without code modifications. Keep in mind that customizations require technical expertise and might need adjustments during Odoo updates.

Hope it helps

I hope this information helps you
