FUNCTION

This attribute tells the coloradjust object for which screen mode the color shall be adjusted. The object queries the display data base for some mode attributes (such as supported number of red/green/blue bits) and adjusts its display accordingly, giving the user an idea of what colors are supported.

Omitting this attribute does not affect the functionality of a coloradjust object. The user will still be able to adjust a color. However, if you know the ModeID, you should supply it.
