There is no adjustment for the yellow. Yellow is normally made by red + green. In the Sharp, it's also

When you set the R, G and B in the panel, the TV is doing a lot of internal magic to determine how much to twist the LC material in the corresponding sub-pixels which will determine how much light gets through. It doesn't actually manipulate the pixels material. So if you make a change to R and G in a Quattron panel. the Sharp might allow more or less light to make it out through the yellow sub-pixels, but it's no trickier than that.
