What is the HSL Secondary section in Lumetri Color?

The HSL Secondary section in Lumetri Color is a powerful tool for fine-tuning specific color ranges in your video footage. It allows you to isolate and adjust the hue, saturation, and luminance of particular colors, offering precise control beyond global color correction. This enables targeted adjustments to skin tones, skies, or any other distinct color element within your scene.

Understanding the HSL Secondary Section in Lumetri Color

The Lumina Color panel in Adobe Premiere Pro is a comprehensive suite for video color grading. Within this panel, the HSL Secondary section stands out as a sophisticated tool for advanced color manipulation. It empowers creators to go beyond basic adjustments and achieve highly specific color corrections and creative looks.

What Exactly is HSL?

HSL stands for Hue, Saturation, and Luminance. These three components are fundamental to understanding and manipulating color:

• Hue: This refers to the pure color itself, like red, green, or blue. It’s what we typically think of when we say "color."
• Saturation: This describes the intensity or purity of a color. A highly saturated color is vivid and strong, while a desaturated color appears muted or closer to gray.
• Luminance: This represents the brightness or lightness of a color. A high luminance means a bright color, and a low luminance means a dark color.

Why Use HSL Secondary?

While the basic color wheels and sliders in Lumetri Color affect the entire image, the HSL Secondary section lets you isolate and modify specific color ranges. This is incredibly useful for:

• Correcting skin tones: You can target the specific orange and yellow hues that make up skin and adjust their saturation or luminance without affecting other colors in the scene.
• Enhancing skies: Isolate blues and adjust their saturation or make them a deeper, more dramatic shade.
• Making specific objects pop: If you have a red car or a green sign, you can make that specific color stand out.
• Creative color grading: Achieve unique looks by selectively altering colors for artistic effect.

Navigating the HSL Secondary Controls

When you open the HSL Secondary section, you’ll find a set of tools designed to help you select and adjust your target colors. It might seem a bit complex at first, but breaking it down makes it manageable.

The Color Picker and Eyedropper Tools

At the heart of the HSL Secondary section are the eyedropper tools. These are your primary instruments for selecting the color you want to adjust.

• Add Eyedropper: Click this tool and then click on the color in your video preview that you want to target.
• Subtract Eyedropper: Use this to deselect colors that may have been inadvertently included in your selection.
• Drag Eyedroppers: You can also click and drag within the color wheel to define a range of hues.

The Color Wheel and Sliders

Once you’ve selected a color range, you’ll see it represented in a color wheel. Below this, you’ll find sliders for Hue, Saturation, and Luminance.

• Hue Slider: Shifts the selected color towards other hues. For example, moving a skin tone slightly might shift it from a peachy tone to a more golden one.
• Saturation Slider: Increases or decreases the intensity of the selected color. Pushing it up makes the color more vibrant; pulling it down makes it more muted.
• Luminance Slider: Brightens or darkens the selected color. This is excellent for subtly lifting shadows or darkening highlights within a specific color range.

The Refine Selection Tools

Crucially, the HSL Secondary section includes tools to refine your color selection. This is where you ensure you’re only affecting the intended colors.

• Color: This slider adjusts the range of hues you’ve selected.
• Saturation: This slider controls the range of saturation within your selection.
• Luminance: This slider defines the range of brightness levels included.

By carefully adjusting these sliders, you can create a very precise mask, ensuring your adjustments are targeted and don’t bleed into unwanted areas of the image. The "Show Color Mask" option is invaluable here, as it visually highlights the area you are affecting.

Practical Applications and Examples

Let’s look at how you might use the HSL Secondary section in real-world scenarios.

Example 1: Enhancing Blue Skies

Imagine a landscape shot where the sky looks a bit washed out.

1. Select the Sky: Use the Add Eyedropper tool to click on the blue sky in your footage.
2. Refine the Selection: Use the Color, Saturation, and Luminance refinement sliders to ensure you’re only affecting the sky and not any nearby clouds or landscape elements. The "Show Color Mask" is essential here to see your selection.
3. Boost Saturation: Gently increase the Saturation slider for the selected blue range to make the sky more vibrant and appealing.
4. Adjust Luminance (Optional): You might slightly lower the Luminance to give the sky more depth or raise it to make it brighter.

Example 2: Correcting Skin Tones

Dealing with slightly off-putting skin tones is common.

1. Target Skin Tones: Use the Add Eyedropper to sample the skin. You’ll likely be targeting a range of oranges and yellows.
2. Isolate the Hue: Adjust the Hue slider for the selected range. You might shift it slightly towards yellow to reduce redness or towards orange to warm it up.
3. Control Saturation: Often, skin tones can be a bit too saturated. Lowering the Saturation slider for the targeted skin range can create a more natural and pleasing look.
4. Fine-tune Luminance: A slight adjustment to Luminance can help bring out detail or smooth out the skin.

Example 3: Making a Red Object Stand Out

Suppose you have a scene with a red sports car, and you want it to be the focal point.

1. Select Red: Use the eyedropper to select the red of the car.
2. Isolate Red: Ensure your selection is tightly focused on the red hue.
3. Increase Saturation: Boost the Saturation slider for the red range to make the car’s color pop dramatically against a more subdued background.
4. Adjust Luminance: You might slightly increase the Luminance of the red to make it brighter and more eye-catching.

Tips for Effective HSL Secondary Use

• Work in a Controlled Environment: Ensure your editing suite has accurate color calibration.
• Use the "Show Color Mask": This is your best friend. It clearly shows you what colors you are selecting and how your adjustments are affecting them.
• Start Broad, Then Refine: Begin with a wider selection and then use the refinement tools to narrow
