I'll let everyone else comment on color settings, but as to sound bars, here's where you can browse through some: http://www.samsung.com/us/video/sound-bars
I just got the 55 ES8000, just started setting it up and was hoping for some help. The speaker volume is kind of low and the sound is not that great, I guess given how thin the TV is. What sound bar might be recommended. In addition what setting will bring the picture closer to the Sony 850 model. I have that in another room and like the colors on it more than what I see on this Samsung model.
