On my Sony TV there is a "Trinitone" (stated as white intensity adjustment). The instruction manual states the following info.: High: Select to give the white colors a blueish tint. Medium: Select to give the white colors a neutral tint. NTSC Standard: Slect to give the white colors a reddish tint. Which is considered "correct"? It would seem NTSC Standard. However, after switching back and forth between "NTSC standard" and "Medium" that the "Medium" is more accurate. Why should white have a reddish tint? Shouldn't white be neutral?
