# QColorConstants Namespace

The QColorConstants namespace contains QColor predefined constants. More...

Header: | #include <QColorConstants>
qmake: | QT += gui
Since: | Qt 5.14

This namespace was introduced in Qt 5.14.

## Detailed Description

These constants are usable everywhere a QColor object is expected:

     painter.setBrush(QColorConstants::Svg::lightblue);

Their usage is much cheaper than e.g. passing a string to QColor's constructor, as they don't require any parsing of the string, and always result in a valid QColor object:

     object.setColor(QColor("lightblue")); // expensive
