Today’s Question: [In Lightroom Classic] can you isolate the Hue you are working on rather than have everything that is that color in your photo be affected?
Tim’s Quick Answer: You can apply adjustments for the hue, saturation, and luminance (brightness) for individual color ranges within Lightroom Classic or Adobe Camera Raw, using the HSL controls.
More Detail: When you adjust the color for a photo using the controls (such as Temp, Tint, and Vibrance) using the Basic set of controls, all colors in the photo are affected. If you want to adjust the appearance of individual ranges of colors, you can instead use the HSL (Hue, Saturation, and Luminance) controls.
If you go to the HSL controls and select “All” just below the heading, you’ll see that there are individual sections for Hue, Saturation, and Luminance. Within those sections there are sliders for the individual color ranges (Red, Orange, Yellow, Green Aqua, Blue, Purple, and Magenta).
You can adjust the hue (essentially the color balance) using the sliders within the Hue section. So, for example, you can make the yellow values within the image appear more green or more orange. Similarly, you can adjust the saturation and luminance for individual ranges of color values.
However, you are not able to alter the ranges of colors. For example, you can’t narrow the range for Orange to ensure you’re not affecting colors that have a bit of a yellow tint to them. The color ranges are essentially locked. Therefore, if you wanted to exercise greater control over the colors in the image, you would either need to apply a targeted adjustment, or send the image to Photoshop so you can exercise more control using the Hue/Saturation adjustment.
