DatePickerModal - Darker primary color on web makes action button unreadable

[jennifer-dickinson]

Current behaviour

When using web to preview the date picker modal and using an MD2 theme, if the theme primary color is a darker shade, the icon buttons on the modal are not visible.

Expected behaviour

The buttons should be visible regardless of platform.

How to reproduce?

1. Have a light theme with a darker primary color such as #0f48a3
2. Preview the app using web
3. Open the date picker modal
4. Observe the action buttons are not legible
