Actually the PreviewPanel is added for all L&F in JDK implementation in BasicColorChooserUI ( see here [L147](https://github.com/kumarabhi006/jdk/blob/70f3e99016311a6520e6a7c0da4c7ff718364976/src/java.desktop/share/classes/javax/swing/plaf/basic/BasicColorChooserUI.java#L147) and [L365](https://github.com/kumarabhi006/jdk/blob/70f3e99016311a6520e6a7c0da4c7ff718364976/src/java.desktop/share/classes/javax/swing/plaf/basic/BasicColorChooserUI.java#L365) ).

So, `setPreviewPanel` should be ok for GTK as well.
