<Tip>
  Choose colors that remain readable in their respective themes—for example, a darker shade for light mode and a slightly brighter or more vibrant shade for dark mode.
</Tip>

## What this changes on your page

Once saved, your custom colors will override the default Cal ID branding in several key areas:

* **Buttons**: Your primary action buttons (like "Confirm") will use your selected brand color.
* **Highlights**: Selected dates and active time slots in the calendar will be highlighted in your brand color.
* **Navigation elements**: Progress bars and specific icons will adopt your custom color scheme.

<Warning>
  To ensure accessibility, avoid using very pale colors (like white or light yellow) as your primary brand color, as they can be difficult to read on light backgrounds. Aim for a contrast ratio that makes your buttons easy to see for all users.
</Warning>
