WarningColor property

TextScreen.WarningColor — Color

The warning color, which is used to paint things like error messages and warning labels, including validation messages of fields.

The warning color is a base color, which other colors may copy or remix. If not set, it inherits the warning color from the preceding screen. If there is no color to inherit, a default color is used, set through the color theme chosen for the app.

You can completely change the color appearance of an app just by setting the primary color, the accent color and the background color. All other colors, if not set explicitly, are based on these base colors. The light foreground color, the dark foreground color and the warning color are also base colors, but rarely need to be changed.

Refer to the examples for the BackgroundColor property for more information on how to set this property dynamically, enabling it to change with values entered by your users.
