[SOLVED]Image color Convert, stumbling upon answer

[2lights]

[Solved]
Changed from QLabel to QGraphicsView

QGraphicsColorizeEffect *effect;
    effect = new QGraphicsColorizeEffect;
 
    effect->setColor(QColor(Qt::red));

QGraphicsColorizeEffect *effect;
    effect = new QGraphicsColorizeEffect;
     
    effect->setColor(QColor(Qt::red));

To copy to clipboard, switch view to plain text mode 

Apologies for any inconvenience
Next time will do my homework better before posting

Kind Regards
