Calibration panel
The calibration panel in Lightroom controls the sliders for the red, green and blue primaries and the shadow tint, right at the bottom of the Develop module. With it you steer the colour base of your photo at the deepest level. Many film looks and custom presets owe their character to this very panel.
Unlike the color mixer, which works per colour, the calibration panel changes the entire colour interpretation from the ground up. Each primary has a hue and saturation slider, plus a separate slider for the tint of the shadows. A small nudge here works through all colours at once, so subtle is the watchword. Tip: use this panel to lay a consistent colour base for your series and do the fine, local corrections afterwards 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.
