\class QColor4ub
\brief The QColor4ub class represents a color by four unsigned byte components.
\since 4.8
\ingroup qt3d
\ingroup qt3d::arrays
OpenGL applications commonly use four unsigned byte values to compactly
represent a color value. QColor4ub provides a convenience
class for manipulating such compact color values.
An alternative is to represent a color value as four floating-point
values between 0.0 and 1.0. The QVector4D class can be used for
that purpose if required.
*/
/*!
\fn QColor4ub::QColor4ub()
Constructs a four-byte default color value of (0, 0, 0, 255).
*/
/*!
\fn QColor4ub::QColor4ub(int red, int green, int blue, int alpha)
