By default, the ForeColor property is 0. The ForeColor property specifies the foreground color to show the time-zone's ShortLabel/LongLabel. The label property may include <fgcolor> HTML tag, which indicates that a portion of the label is being displayed with a different foreground color. So, if changing the time-zone's ForeColor is not showing any difference, please check the Label property if it contains any color attributes like <fgcolor>, <bgcolor>. The Label property specifies the label to be displayed on the time-zone.
