Drop a Button
Open the CSS Analyzer
Filter "text-fill" to display only the -fx-text-fill property
Click on the Lookup visual: the content shows only -fx-color>fx-base (see attached screenshot).
According modena.css, it should be -fx-text-base-color, which is defined as:
-fx-text-base-color: ladder(
        -fx-color,
        -fx-light-text-color 45%,
        -fx-dark-text-color 46%,
        -fx-dark-text-color 59%,
        -fx-mid-text-color 60%
    );

This is a regression compared to SB 1.1
