Click the eyedropper icon in the toolbar, then click and drag on the viewer to select the color range you want to adjust. The selection appears highlighted in the hue, saturation, and luminance strips in the qualifier palette. Click the magic wand icon in the viewer to see the selection as a black-and-white key. Use the qualifier controls to refine the selection, then adjust the image using wheels, curves, or any grading tool. ![Secondary Correction](https://images.blackmagicdesign.com/images/products/davinciresolve/color/correction/correction-xl@2x.jpg?_v=1649313180) Qualifiers target areas based on color properties — hue, saturation, and luminance — rather than spatial position. This makes them ideal for adjusting specific elements within a scene: changing the color of a shirt without affecting skin tones, darkening a blue sky while leaving the clouds untouched, or boosting the saturation of a red car. ## How do you refine a qualifier selection in Resolve? After making an initial selection, the qualifier palette shows three histogram strips for hue, saturation, and luminance. The highlighted area represents your current selection. Use the selection range sliders below each strip to expand or contract the selected range. The softness controls (low and high) create smooth transitions at the edges of the selection. The 3D qualifier mode provides even more precise control. It displays your selection in a 3D color space where you can see exactly which colors are included. Drag control points to refine the selection boundaries in three dimensions. This is the most accurate way to isolate colors that are close to each other in hue space — for example, separating a specific shade of green foliage from a slightly different green background. Clean up the key using the blur, dilate, and erode controls. Blur softens the edges of the key for natural transitions. Dilate expands the key to include more edge pixels. Erode contracts it to tighten the selection around hard edges. The highlight, shadow, and gamma controls adjust the tonal distribution of the key for fine edge control. ## How do you qualify specific objects without affecting skin tones? Skin tones occupy a specific hue range — typically around orange-red. To qualify a shirt without affecting skin, use the eyedropper to select the shirt color, then look at the hue selection strip. Skin tone hues should fall outside the selected range. If skin tones are partially selected, contract the hue range or use a qualifier with a power window to limit the selection to the shirt's spatial area. The combination of qualifiers and power windows is the standard approach for complex secondaries. Use the power window to roughly define the spatial area of the shirt, then use the qualifier within that window to select the exact color. The window prevents the qualifier from accidentally selecting similar colors elsewhere in the frame. ## FAQ ### What is the difference between a qualifier and a power window? A qualifier selects by color properties (hue, saturation, luminance). A power window selects by spatial position (shape on screen). Use qualifiers for color-based selections and power windows for object-based selections. ### Can I use qualifiers on the free version of DaVinci Resolve? Yes. Qualifiers are available in both free and Studio versions. ### How do I view the key as an alpha channel? Click the magic wand icon in the viewer toolbar to toggle the key display. White areas are fully selected, black areas are unselected, and gray areas are partially selected. ### Can I keyframe qualifier settings? Yes. Qualifier parameters can be keyframed to track changing colors across a clip. ### What is the 3D qualifier and when should I use it? The 3D qualifier displays the selection in a three-dimensional color space for more precise boundary definition. Use it when standard HSL qualifiers cannot cleanly separate similar colors.
