--- Comment #2 from Esme Povirk madewokherd@gmail.com --- I did a quick test setting ForeColor on a CheckBox (there is no Foreground property), and I do not see this behavior regardless of whether I have a theme enabled. But I'm now realizing, you didn't specify what toolkit you were using. My test was with System.Windows.Forms.
