    \ingroup qtquick-visual
    \brief The set of colors by roles.

    The ColorGroup type is used to define a set of colors with certain roles. Although a ColorGroup
    has no visual appearance, it defines colors used to customize rendered items.

    Default values of colors are equal to active group colors of default-constructed \c QPalette.

    The following code can be used to create a color group with some colors specified:

    \code
    ColorGroup {
        alternateBase: "red"
        base: "green"
    }
    \endcode

    The \l Palette type exposes color groups for each QML item state.
 */

/*!
    \qmlproperty color QtQuick::ColorGroup::accent
    \since 6.6

    A color that typically contrasts or compliments \l base, \l window, and \l
    button colors. It usually represents the users' choice of desktop
    personalisation. Styling of interactive components is a typical use case.
    Unless explicitly set, it defaults to \l highlight.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::alternateBase

    Used as the alternate background color in item views with alternating row colors.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::base

    Used mostly as the background color for text editor controls and item views.
    It is usually white or another light color.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::brightText

    A text color that is very different from \c windowText, and contrasts
    well with e.g. \c dark. Typically used for text that needs to be drawn
    where \c text, \c windowText or \c buttonText would
    give poor contrast, such as on highlighted buttons.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::button

    The general button background color. This background can be different from
    \c window as some styles require a different background color for buttons.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::buttonText

    A foreground color used with the \c palette color.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::dark

    A foreground color used with the \c palette color.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::highlight

    A color to indicate a selected item or the current item.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::highlightedText

    A text color that contrasts with \c highlight.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::light

    Lighter than \c button.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::link

    A text color used for hyperlinks.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::linkVisited

    A text color used for already visited hyperlinks.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::mid

    Between \c palette.button and \c dark.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::midlight

    Between \c button and \c light.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::shadow

    A very dark color.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::text

    The foreground color used with \c base. This is usually the same as
    the \c windowText, in which case it must provide good contrast with
    \c window and \c base.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::toolTipBase

    Used as the background color for tooltips.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::toolTipText

    Used as the foreground color for tooltips.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::window

    A general background color.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::windowText

    A general foreground color.
*/

/*!
    \qmlproperty color QtQuick::ColorGroup::placeholderText
    \since 6.2

    Used as the place holder color for editable single line fields.
*/

/*!
    \qmlsignal QtQuick::ColorGroup::changed

    Additional signal indicates that the current state of this color group
    has been changed. Usually it means that one of the colors is changed.

    Construct object in default state.
