I’ve written quite a bit about using curves to adjust tonality and brightness but curves can be a lot more flexible tools than this. The fact that curves are split into red, green and blue components allows us to adjust the tone of a picture and to do so at various brightness points. So, for instance, we can change the colour of the shadows in one direction whilst changing the highlights in another direction (e.g. cool shadows, warm highlights but leave midtones alone). This is particularly apt as Lightroom now includes curves adjustments of the red, green and blue channels in a similar way to Photoshop.
