Lightroom is a nuanced application full of controls, sections, subcontrols, subsections, sub-sub- well, you get my point. One of the least often examined tabs is buried at the bottom of the Develop Module: the Camera Calibration tab. This video gives a helpful explanation of exactly what that tab controls.
If you think about what "blue" really is, it's just a word that was arbitrarily agreed upon to represent an approximate wavelength of the visual light spectrum. The problem is that my blue might not be your blue, which might not be Nikon's blue, etc.. This is where the Camera Calibration tab comes into play in Lightroom. As Anthony Morganti explains in this helpful video, the Camera Calibration tab is what sets exactly what the three primary colors (red, blue, and green) are for a specific photo, from which all other colors are formed via combinations thereof. It also allows you to change the saturation of each primary color and also to access your camera's built-in picture profiles to apply them to a raw image within the app. While it's not a tab you'll likely often use, if you find your raw files consistently don't quite have the balance of colors you like or you'd like you use a profile from your camera, it's a good one to know.
