How do I use the HSL Secondary in the Lumetri Color Panel?

The HSL Secondary in the Lumetri Color panel allows you to precisely target and adjust specific colors within your video footage. This powerful tool enables you to fine-tune hues, saturation, and luminance for individual color ranges, offering granular control over your color grading.

Mastering the HSL Secondary in Lumetri Color

The Lumetri Color panel in Adobe Premiere Pro is a robust suite for video color correction and grading. Within it, the HSL Secondary section stands out as a particularly potent tool for advanced users. It allows for targeted color adjustments, meaning you can modify a specific color without affecting the rest of your image. This is crucial for achieving professional-looking results and correcting challenging lighting scenarios.

What is HSL Secondary and Why Use It?

HSL stands for Hue, Saturation, and Luminance. The HSL Secondary feature lets you isolate a particular color range (like blues in the sky or greens in foliage) and then adjust its hue, saturation, or luminance independently. This is incredibly useful for:

• Correcting skin tones: You can easily desaturate or shift the hue of unwanted green or magenta casts in people’s skin.
• Enhancing specific elements: Make the sky a richer blue or the grass a more vibrant green.
• Creating specific looks: Push colors in unique directions for artistic effect.
• Fixing color casts: Remove color casts from mixed lighting conditions.

How to Access and Use HSL Secondary

Locating and utilizing the HSL Secondary is straightforward once you know where to look.

1. Open Lumetri Color: Select your clip in Premiere Pro’s timeline. Then, go to Window > Lumetri Color.
2. Navigate to HSL Secondary: Within the Lumetri Color panel, scroll down to the HSL Secondary section. You’ll see it listed below Basic Correction, Creative, Curves, and Color Wheels.
3. Select Your Target Color: The core of HSL Secondary is the color picker tool. Click the eyedropper icon. Then, click directly on the color in your video preview that you want to adjust. You can click and drag slightly to select a broader range of that color.
4. Refine the Selection: Below the eyedropper, you’ll find three sliders: Hue, Saturation, and Luminance. These initially represent the range of the color you picked. Use the Color Tolerance (Hue, Saturation, Luminance) sliders to expand or contract the selection. The Key Output option (initially set to "Color/Gray") is vital here.

Understanding Key Output

The Key Output setting is your visual guide.

• Color/Gray: This is the default. It shows your video with the selected color range appearing in color and everything else in grayscale. This is the most intuitive way to see what you’re affecting.
• Color/Black & White: Similar to Color/Gray, but the unaffected areas are pure black.
• Gray/Color: Inverts the previous view. Unaffected areas are gray, and the selected color range is desaturated.
• Black & White: Shows only the selected color range in grayscale, with everything else black. This is useful for seeing the precise mask you’ve created.

Use the Color Tolerance sliders to make the colored area in the "Color/Gray" view perfectly match the object you want to adjust. You want the object to be brightly colored and the background to be as gray as possible.

Adjusting Hue, Saturation, and Luminance

Once you have a clean selection, you can start making your adjustments.

• Hue: This slider shifts the color itself. Moving it left or right will change the color’s position on the color wheel. For example, you can shift a greenish skin tone towards yellow or red.
• Saturation: This slider controls the intensity of the color. Pushing it up makes the color more vibrant; pulling it down desaturates it, eventually turning it to gray.
• Luminance: This slider adjusts the brightness of the selected color. You can make a specific color lighter or darker.

Practical Examples in Action

Let’s say you have a shot with a slightly washed-out blue sky, and you want it to pop.

1. Select the eyedropper in HSL Secondary.
2. Click on the blue sky in your video.
3. Switch Key Output to "Color/Gray."
4. Adjust the Hue, Saturation, and Luminance Tolerance sliders until only the sky is brightly colored, and the rest of the image is gray.
5. Switch Key Output back to "Color/Gray" for normal viewing.
6. Now, use the main Hue, Saturation, and Luminance sliders for the selected color range. Increase the Saturation to make the blue more intense. You might also slightly shift the Hue to a richer, deeper blue.

Another common scenario is correcting skin tones. Often, outdoor shots can pick up a green cast from foliage.

1. Use the eyedropper on the person’s skin.
2. Refine the selection using Tolerance sliders until the skin is well-represented and other colors are gray.
3. Switch Key Output to "Color/Gray."
4. You’ll likely want to slightly adjust the Hue slider to move away from green and towards a more natural skin tone. You might also slightly decrease Saturation if the skin appears too vivid.

Advanced Techniques and Tips

• Feathering: Use the Feather slider to soften the edges of your color selection. This helps blend the adjustment more naturally into the image.
• Shrink/Expand: These sliders can help refine the mask’s edges, especially if your initial selection is slightly too large or small.
• Multiple HSL Secondaries: You can actually create multiple HSL Secondary adjustments on a single clip. This allows you to target different colors independently. For instance, you could enhance the sky and correct skin tones in separate HSL Secondary sections.
• Combine with Other Lumetri Tools: The HSL Secondary works best when combined with other Lumetri tools. Start with basic corrections, then use HSL Secondary for specific color work, and finally, add creative looks or final touches.

When to Use HSL Secondary vs. Color Wheels

While Color Wheels offer broad adjustments, HSL Secondary provides precise control over specific colors. Use Color Wheels for overall color balance and mood. Reserve HSL Secondary for when you need to isolate and manipulate a particular hue, saturation, or luminance value without impacting other parts of the image.
