Calibration
The calibration panel in Lightroom adjusts the base colours of your RAW via the red, green and blue primaries. With hue and saturation sliders per primary you change the colour base of the whole image in a deep, cohesive way. It's a powerful place to set your own colour character.
Unlike the color mixer, which works per colour, calibration steers the entire colour interpretation from the ground up. Many classic film looks and presets use this very panel for their typical colour feel. A small nudge on the blue primary saturation, for example, quickly gives richer, fuller colours. Tip: use calibration subtly as a base layer under your look, then fine-tune with the color mixer.

The presets on this site set these adjustments up for you as a starting point, which you then fine-tune to taste.
