You could use the Tone Curve’s individual colour channels, or the often-missed Calibration panel. Even the HSL panel can be used for creative rather than corrective means. Here, though, you’ll see the Color Grading panel in action. Located in the Develop module, Color Grading makes use of three colour wheels: Shadows, Midtones and Highlights. The dot in each allows for simultaneous Hue and Saturation changes, while a slider below handles Luminosity changes. Holding down Shift while dragging the dot limits you to Saturation; holding the Command or Control key limits it to Hue only. In the individual views, you can click the disclosure triangle below the wheel to see all three control sliders. Open up the Lightroom.jpg start file, or one of your own images to begin.
