Applies to Gauge and Bullet visuals.
To choose a different color for the value on the Measurement shelf, navigate to the Colors settings, and make changes in the Foreground Color selector. You can select one of the palette colors, or specify a custom color.
Note how the change in foreground color changes the gauge visual; the main measurement that this option affects is on the inner arc.
Note how the change in foreground color changes the bullet visual; the main measurement is the narrow central bar.
