On this version of the LG CMS, only "tint" is of any significant use.
LG "Tint" = hue (angle)
LG "Color" = Lightness (it also effects "saturation," but not in any useful way.)
Furthermore, you can't really move the 100% saturated primaries. If you're going to have any success at all with the CMS controls, you'll need to use 75% Saturated targets which are *not* available on the set's built in "expert patterns." (Locate, the AVS-HD test disk and burn yourself a copy.)
I use the tint controls to set up the six color hue angles, then call it quits (the color controls should be pretty much dead on if you leave them at 0.)
