Your code is almost correct. Only QLine edit uses the Base color. So if you do not want to replace existing stylesheet which can contain borders padding and margin and you want to change background only, use QPalette:

palette.setColor(QPalette::Base, Qt::green);
_ui->lnSearch->setPalette(palette);
