How do I use the Hue vs. Hue curve in Lumetri Color?

The Hue vs. Hue curve in Adobe Premiere Pro’s Lumetri Color panel allows you to shift specific color ranges to different hues, effectively changing their colors. This powerful tool is ideal for subtle color correction, creative color grading, and isolating specific colors for emphasis or removal.

Mastering the Hue vs. Hue Curve in Lumetri Color

The Lumetri Color panel in Adobe Premiere Pro is a robust suite of tools for color correction and grading. Among its many features, the Hue vs. Hue curve stands out for its precision in manipulating color. This curve offers a granular approach to changing specific colors within your footage without affecting others.

Understanding Color Wheels and Curves

Before diving into the Hue vs. Hue curve, it’s helpful to understand how color is represented. In Lumetri Color, you’ll often encounter color wheels, which provide a broader way to adjust color casts. Curves, however, offer more precise control. The Hue vs. Hue curve specifically targets the hue of colors, which is their pure color name (like red, blue, green).

How the Hue vs. Hue Curve Works

The Hue vs. Hue curve plots the original hue on the horizontal axis and the new hue on the vertical axis. By default, the curve is a straight diagonal line. This means that if you don’t adjust it, the hue remains unchanged.

To modify a color, you’ll add points to this curve. When you drag a point up or down, you are changing the hue of the color that corresponds to that point on the horizontal axis.

Key Concepts:

• Horizontal Axis (Input): Represents the original hue of the pixels in your video.
• Vertical Axis (Output): Represents the new hue you want to assign to those pixels.
• Points on the Curve: Each point allows you to isolate and adjust a specific hue range.

Practical Applications for the Hue vs. Hue Curve

This tool is incredibly versatile. Here are a few ways you can leverage the Hue vs. Hue curve:

• Correcting Skin Tones: If your subject’s skin has an undesirable green or magenta cast, you can use the curve to shift that specific hue range towards a more natural tone. This is a common color correction technique.
• Creative Color Grading: Want to make all the blues in your shot appear more teal? Or perhaps turn a red object into an orange one? The Hue vs. Hue curve makes these creative color shifts possible.
• Isolating and Desaturating Colors: You can use the curve to target a specific color and shift its hue so drastically that it becomes desaturated or even blends into another color, effectively removing it from the scene. This is useful for removing distracting elements.
• Enhancing Specific Colors: Conversely, you can subtly shift a color to make it stand out more, adding visual interest to your footage. This can be a powerful tool for cinematic color grading.

Step-by-Step Guide to Using the Hue vs. Hue Curve

Let’s walk through a common scenario: adjusting the hue of blue objects.

1. Open Lumetri Color: Select your clip in Premiere Pro and open the Lumetri Color panel.
2. Navigate to Curves: Expand the "Curves" section.
3. Select Hue Curves: Click on the dropdown menu and choose "Hue/Saturation".
4. Choose Hue vs. Hue: Select the "Hue vs. Hue" option.
5. Identify the Target Hue: Look at your video and identify the color you want to change. For example, if you want to change the blue of a shirt.
6. Add a Point: Click on the curve directly above the blue range on the horizontal axis. You’ll see a point appear.
7. Adjust the Hue: Click and drag this point upwards or downwards. Dragging it up will shift the hue towards magenta/red. Dragging it down will shift it towards green/cyan.
8. Refine with Additional Points: You might need to add two more points on either side of your initial point to create a subtle "S" or inverted "S" shape. This helps to isolate the color adjustment and prevent unintended color shifts in adjacent hues.
9. Use the Eyedropper Tool: For even greater precision, use the eyedropper tool within the Hue vs. Hue curve section. Click on the color in your video you want to adjust, and Lumetri will automatically place a point on the curve for you. You can add up to three points using the eyedropper to define a specific color range.

When to Use Hue vs. Hue vs. Other Curves

Lumetri Color offers several curve options. Understanding their differences helps you choose the right tool for the job.

Tips for Effective Hue vs. Hue Curve Usage

• Start Subtle: Always begin with small adjustments. It’s easier to add more intensity than to undo an over-processed look.
• Zoom In: When working with the curve, zoom into your video to see the subtle changes more clearly.
• Watch for Artifacts: Over-manipulating the curve can lead to color banding or unnatural shifts. Keep an eye out for these visual glitches.
• Combine with Other Tools: The Hue vs. Hue curve works best when used in conjunction with other Lumetri Color tools like the basic correction, curves, and HSL secondary adjustments.
• Consider the Context: Think about how the color shift will affect the overall mood and message of your video.
