The Hue Saturation Curves within the Lumetri Color panel are specifically designed for secondary color correction. This allows an editor to isolate a specific color range (a hue) and adjust its properties independently. To change the color of the sky, one would use the "Hue vs Sat" curve to select the blue hue of the sky and then increase or decrease its saturation, or the "Hue vs Hue" curve to shift its color (e.g., from cyan to a deeper blue) without affecting other colors in the clip. This tool provides the precise, targeted control required by the question.

A. In the Lumetri Color Panel, use the White Balance Selector.

The White Balance Selector is a global tool used to correct a color cast across the entire image by setting a neutral reference point; it does not isolate a single color.

C. Apply the Leave Color Effect to the dip.

The Leave Color effect is a stylistic tool that desaturates all colors in the clip except for the selected one, which is not the same as subtly adjusting a specific color.

D. Change the clip Blend Mode to Multiply.

Blend modes determine how a clip interacts with the clips on tracks below it. They do not provide tools for selective color adjustment within the clip itself.

1. Adobe Premiere Pro User Guide

"Curves color correction adjustment controls." This official documentation details the function of the Hue Saturation Curves. It states

"Use the Hue vs Sat curve to adjust the saturation of a color. For example

you can bring out the blue in the sky without affecting other colors in the image." This directly supports the correct answer (B).

2. Adobe Premiere Pro User Guide

"Basic Correction controls." This section explains the White Balance (WB) Selector's function: "To automatically adjust white balance

click the WB Selector eyedropper

and then click on an object in the image that should be white

gray

or black." This confirms it is a global correction tool

making option (A) incorrect.

3. Adobe Premiere Pro User Guide

"List of video effects." The "Leave Color" effect is listed under the "Obsolete" category. Its function is described as creating a grayscale image with one color left

which is a specific creative effect

not a general adjustment tool

making option (C) unsuitable for the task.

4. Adobe Premiere Pro User Guide

"Blending modes." This guide explains that blending modes "determine how a clip on a video track blends with

or reacts to

clips on the tracks below it." This confirms that blend modes are for layer interaction

not for selective color correction within a single clip

making option (D) incorrect.
