Using default wxWidgets class wxColourPickerCtrl gives very poor (see picture bellow) results under Mac OS, so we have made a new class called tmColourPickerCtrl based on :

wxBitmapButton : for Mac
wxColourPickerCtrl : for Linux and Windows

tmColourPickerCtrl is very simillar to wxColourPickerCtrl and same methods may be used such as GetColour() or SetColour() for getting or setting colours from the control.
