Question details

Users need a way to increase the color contrast between available and unavailable time slots in Microsoft Bookings for better visual accessibility.

How to Improve Available and Unavailable Time Contrast in Microsoft Bookings

Product: Microsoft Bookings
Device & OS: not provided
Scenario: Viewing and managing the booking schedule on the calendar page.
Observed behavior: Available and unavailable hours use very similar colors, making it difficult for users with visual impairments or color blindness to distinguish between them.

Before you start

Log in to your Microsoft Bookings account as an administrator, as appearance and theme settings can only be adjusted by users with admin or page owner privileges.

Solution 1Recommended

Adjust Microsoft Bookings Theme Settings

Switching between available light, dark, or classic themes may slightly improve readability depending on your screen settings and visual preferences.

Microsoft Bookings currently offers limited customization for calendar colors. While you cannot set independent colors for time slots, toggling the built-in themes is the fastest way to alter the overall visual contrast.

Access Booking Page Settings

Open Microsoft Bookings and navigate to the 'Booking page' tab from the left-hand menu.

Locate Appearance Options

Scroll down to the 'Customize your page' or 'Appearance' section on the settings page.

Toggle Display Themes

Select different options such as Light mode, Dark mode, or Classic themes (like black or blue) to see which provides the best contrast for your vision.

Save and Test

Click 'Save' at the top of the page, then open your published booking page to test if the calendar view is easier to read.

Adjust Microsoft Bookings Theme Settings

Limitation: Currently, Microsoft Bookings does not allow custom hex color selection specifically for the available vs. unavailable time blocks.

Solution 2

Request Accessibility Features in Microsoft Tech Community

Since native custom color options are missing, escalating the accessibility concern to Microsoft engineers is the official path to request a fix.

Frequently Asked Questions

Can I set custom hex colors for available and unavailable times in Microsoft Bookings?

No, Microsoft Bookings currently limits color customization to overarching page themes and does not support granular hex color changes specifically for time blocks.

Does the dark mode in Microsoft Bookings fix the contrast issue?

While dark mode changes the overall background and surrounding interface, many users report that the contrast between available and unavailable time slots in the calendar itself remains difficult to distinguish.

Can page templates change the calendar area colors?

No, page templates in Microsoft Bookings generally apply to the header and overall booking page styling, but they do not alter the specific colors used inside the calendar area.

How can I improve scheduling accessibility for my clients in the meantime?

Until Microsoft introduces better color contrast, consider clearly stating your typical available hours in plain text within the booking page description to assist visually impaired clients.
