FColors class final

A set of colors that is part of a FThemeData. It is used to configure the color properties of Forui widgets.

These properties are not used directly by Forui widgets. Instead, they are the defaults for the corresponding colors of widget styles configured via inherit(...) constructors.

The main color groups in this scheme are primary, secondary, muted, destructive, and error.

  • Primary colors are used for key widgets across the UI.
  • Secondary colors are used for less prominent widgets.
  • Mute colors are typically used for disabled widgets.
  • Destructive colors are used for destructive actions such as "Delete" buttons.
  • Error colors are typically used to highlight errors, such as invalid input in text-fields.

Each color group includes a -Foreground suffixed color, i.e. primaryForeground, used to color text and other visual elements on top of their respective background colors.

Hovered colors are derived by adjusting the lightness of the original color. To derive these colors, use the hover method. The lightness can be adjusted with hoverLighten.

Disabled colors are derived by adjusting the opacity. To derive these colors, use the disable method. The opacity can be adjusted with disabledOpacity.

See FThemes for predefined themes and color schemes.
