clWindow = mostly edit controls, comboboxes, and scrollviews.
clForm,clBackground = same colors, general widgets color (TCustomForm, TPanel 
etc ..)
clBtnFace = all kind of buttons ...

under qt it's clear
clWindow = QPaletteBase (QLineEdit, QComboBox, QTextEdit).
clForm,clBackground = QPaletteWindow (GENERAL WIDGET COLOR. QWidget, QLabel -> 
TStaticText, QFrame etc ...)
clBtnFace = QPaletteButton (generally all types of buttons -> QPushButton, 
QCheckBox, QRadioButton etc .....).

definitelly clBtnFace is wrong as default for general widgets (in CLX 
clBackground is default color for such widgets).
 
One more thing. There are GTK2 related colors bugs #7555,#9945 (also I cannot 
rework some things under Qt palettes) because of this unclear situation.

yes , they are confusing because they are incorrect.
