groups.	But	they	will	be	same	under	same	source.

When	we	adjust	color	setting	the	current	color	temperature	will	be	
memorized	before	it	auto	switch	to	“User”.	Because	the	memo-
rized	color	temperature	will	be	a	base	of	“User”.	For	example:
1.) Colour temp. is Low.
2.) User create his favorite color based on “Low” setting of colour 
temperature.	So	when	user	switch	“Colour	temp.”	to	“User”,	
will find the image color temperature close to “Low”.
