I use Offset / Gain to move the RGB tracking levels to the best overall, Slightly low at black (1) because there is only gain and slightly high at white (8) because there is only cut.
If you use HCFR for this, you can type 8 into the preference box rather than use the more common 10 step process.
There are settings +2, +1, 0, -1, -2, Custom
-2 equates to about 2.3-2.4 as a rough setting, though custom gives the opportunity to balance out the gamma more correctly
Used to correct the colour component. There is Hue, Saturation and Brightness (Luminance) for each of the Primaries and Secondaries. Roughly hue is how much of the colour there is, Saturation how much grey and Brightness how much white. The first two move the colour on the Gamut Chart (colour space) and Brightness is involved with lumenance error. All three impact on the overall error Delta e.
