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
