Color mixer
The Color Mixer is the modern name for the HSL panel in Lightroom: here you control hue, saturation and luminance per color. Some versions also offer a point color mode that lets you pick an exact color from the photo and adjust it. It's your tool for precise color work.
Use the color mixer to make colors consistent across a series: pull all your greens to the same hue, for example. The targeted adjustment tool lets you drag directly on the photo, handy when you're not sure which color slider you need. In point color mode you can isolate a very specific tint, like exactly that one orange of a sweater. Work subtly, because big color shifts show up fast.
