As if source list color superimposes on the area other than the text field.

The only documentation I have been able to find about NSVisualEffectView is (1) in the AppKit release note for Yosemite (which apparently is still only available for Developer Preview 5) and (2) in the NSVisualEffectView reference document. In one of those documents, there is some discussion of what you have to do to avoid unwanted color changes in text fields with NSVisualEffectView in back.
I think you override -(BOOL) allowsVibrancy to return NO to turn off the NSVisualEffectView’s … err … effect.
