How to programmatically set the color or texture of a tab label in JavaFX?

Question

I have a TabPane with several Tabs. If the results of an operation in the Tab failed, I want to set the Tab Label to a Fill red or perhaps the texture to hashed (for those with color blindness). I want to reset the Color back to its default, later.

From reading some of the questions here, one can statically set it using a style sheet.

#MyTabPane .tab *.tab-label {
    -fx-text-fill: white;
}

How would one access the Tab label and set it's color/texture dynamically?

tab.setStyle("??");

Setting the graphics and styling it did the trick for me:

Tab tabB = new Tab();
tabB.setText("");
tabPane.getTabs().add(tabB);
tabB.setStyle("-fx-border-color:red; -fx-background-color: blue;");
tabB.setGraphic(new Label("Tab B"));
tabB.getGraphic().setStyle("-fx-text-fill: #c4d8de;");

Thanks. Surprisingly, if you do tab1.setGraphic(imageView), and then tab2.setGraphic(imageView), the graphic switches from tab1 to tab2. Only one tab has the graphic. – Whomp

This is not surprisingly, because a Node can always be only once in the SceneGraph. A "graphic" is a generic Node in the SceneGraph like any Node. – Spring

which makes you wonder why they call it a 'graph' in the first place. But well, yes it is a true, so it is not surprising that the ImageView can only have 1 parent. – Worldlywise
