This solution is based on @Chris' solution

 if (checkCombo.getCheckModel().isChecked(0)) {
    lineChart.getData().add(seriesTest1);
    changeColorSeries(lineChart.getData().size() - 1, "darkgreen");
 }

 if (checkCombo.getCheckModel().isChecked(3)) {
    lineChart.getData().add(seriesTest2);
    changeColorSeries(lineChart.getData().size() - 1, "darkred");
 }

 private void changeColor(int position, String color) {
        Platform.runLater(() -> {
            Node nl = lineChart.lookup(".default-color" + position + ".chart-series-line");
            Node ns = lineChart.lookup(".default-color" + position + ".chart-line-symbol");
            Node nsl = lineChart.lookup(".default-color" + position + ".chart-legend-item-symbol");

            nl.setStyle("-fx-stroke: " + color + ";");
            ns.setStyle("-fx-background-color: " + color + ", white;");
            nsl.setStyle("-fx-background-color: " + color + ", white;");
        });
 }
