Color Wheels represent the most fundamental color grading tool available in virtually every post-production software on the market. Despite their apparent simplicity, they are remarkably powerful and, when used skillfully, can serve as the primary tool for complete color correction work.
Many colorists who have worked with these tools for years find themselves relying almost exclusively on the wheels for their corrections. The key to mastering color grading is not necessarily knowing every tool available, but rather focusing on a select few tools and learning them thoroughly. Color Wheels, combined with HSL keying, can handle the vast majority of color correction needs across entire projects.
This tutorial explores the three main types of Color Wheels available in DaVinci Resolve: the standard Color Wheels, LOG Wheels, and HDR Wheels. Each type operates differently and serves specific purposes in the color grading workflow. Understanding when and how to use each type will significantly improve your ability to achieve professional-looking results.
Color Wheels: Fundamentals and Usage
Color Wheels in DaVinci Resolve divide the image into three sections based on pixel luminosity. The first wheel, called LIFT, controls the darker portions of the image and the black point. The middle wheel, GAMMA, controls the center of the image where middle gray resides. Since most image information typically falls within the middle of the luminosity spectrum, the GAMMA wheel exerts the strongest effect on the overall image. The third wheel, GAIN, affects the brighter portions of the image and the white point. A fourth control, OFFSET, affects the entire image uniformly.
Each wheel provides two primary methods for modifying the image. The first is exposure control, managed through a slider mechanism. Moving the GAMMA exposure control to the right brightens the image starting from middle gray, while moving it left darkens the image. Each wheel has its own exposure control: LIFT for blacks, GAMMA for midtones, and GAIN for highlights. These three controls behave like an elastic band, dragging the entire image up or down relative to their specific luminosity range. OFFSET, in contrast, simply slides the entire image upwards or downwards without this elastic behavior.
The second method of modification is color correction, achieved by manipulating the dot in the center of each wheel. Pushing the dot in a particular direction adds that color to the image, while pushing it in the opposite direction removes unwanted color casts. The dot can be quite sensitive, so beginners should use incremental movements at 90-degree angles to maintain control. Double-clicking on the dot resets both the color and exposure adjustments for that wheel.
The division of color control follows the same luminosity-based structure as exposure. LIFT affects the blacks, GAMMA affects the midtones, and GAIN affects the highlights. Since most image information resides in the GAMMA range, this wheel applies the most noticeable color correction to the image. OFFSET moves color across the entire image, which often introduces unwanted color shifts in both highlights and shadows, making it less useful for targeted color work.
For more precise control, sliders beneath each wheel allow color adjustments along specific axes. The Red slider moves along the Red-Cyan axis, Green along the Green-Magenta axis, and Blue along the Blue-Yellow axis. This provides an alternative to the circular wheel interface when exact values are needed.
Color Wheels excel at fixing general luminosity and defining scene contrast. They are forgiving tools that accommodate larger adjustments without introducing artifacts. OFFSET works particularly well as an initial tool for roughly placing exposure where desired without modifying the clip’s inherent contrast. For practical examples of these techniques applied to real footage, watch the corresponding sections in the video tutorial.
LOG Wheels: Precision Control
LOG Wheels initially appear identical to standard Color Wheels, but they function fundamentally differently. The image is still divided into three parts—Shadows, Midtones, and Highlights—but these sections do not interact with each other in the same way as Color Wheels.
When adjusting the exposure wheel in Midtones, only the midtone section of the image moves up or down, without dragging the rest of the image along. The same principle applies to Shadows, which only affect the lower portion of the image, and Highlights, which only modify the upper portion. This segmented approach contrasts sharply with Color Wheels, where adjusting one region affects adjacent regions.
The cutting points between these segments are defined by Range parameters. The first Range parameter indicates where Shadows and Midtones are separated, while the second parameter defines the boundary between Midtones and Highlights. Adjusting these range parameters can significantly alter how the wheels affect the image, providing additional control over which parts of the luminosity spectrum are modified.
This isolated behavior makes LOG Wheels more precise but also potentially more problematic if used incorrectly. While Color Wheels provide a stronger and more forgiving correction suitable for broad adjustments, LOG Wheels excel at minor, targeted adjustments. They work particularly well for placing a cap on highlights or positioning black levels at specific values without affecting the rest of the image.
The same color correction principles apply to LOG Wheels as to Color Wheels, with the dot in the center of each wheel controlling color shifts. However, because of the segmented nature of LOG Wheels, color corrections are more subtle and confined to their specific luminosity range. The Shadows wheel proves especially useful for removing color spill from blacks, helping to maintain clean, neutral shadows.
LOG Wheels should be approached as a tool for refinement rather than broad correction. They work best for final touches after primary corrections have been established with Color Wheels. Attempting to use LOG Wheels for major exposure or color shifts can result in unnatural-looking images with visible transitions between luminosity zones. For practical demonstrations of LOG Wheels in action, refer to the video tutorial sections showing before-and-after comparisons.
HDR Wheels: Extended Dynamic Range Control
HDR Wheels operate within a High Dynamic Range (HDR) workflow, which utilizes a broader luminosity range than the Standard Dynamic Range (SDR) used for most content. While SDR remains the dominant format for most transmissions and displays, HDR provides greater definition between the deepest blacks and brightest whites, resulting in a more detailed, less contrasted image.
The primary distinction of HDR Wheels is their division of the image into six sections instead of three. Three controls are directly visible, with three additional controls accessible through interface elements. These wheels operate in a manner that falls between standard Color Wheels and LOG Wheels—each control modifies a specific portion of the image while also affecting adjacent regions to some degree.
Shadows correct the bottom half of the image, while Light corrects the top half. Highlights modify the top 25% of the image, while Dark modifies the bottom 25%. Blacks touch approximately the bottom 5% of the image, and Specular affects only the very brightest portions, which may exceed 100% white in HDR content. The Specular control is particularly useful for recovering detail in the highest portions of the spectrum when working with footage shot in HDR.
Another significant difference between Color Wheels and HDR Wheels is the separation of saturation and luminosity. In standard Color Wheels, increasing GAMMA tends to add saturation as well, and adding saturation tends to brighten the image. HDR Wheels work within a color space that separates these two properties, making saturation adjustments more accurate and predictable.
HDR Wheels prove particularly valuable when working with footage that has lost detail in shadows or highlights due to aggressive primary corrections. The multiple control points allow for nuanced recovery of detail in specific luminosity ranges without affecting the entire image. They work well in combination with other wheel types: Color Wheels for rough exposure correction, HDR Wheels for contrast adjustment, and LOG Wheels for final touches.
The increased number of controls requires more careful attention to avoid overcorrection. Each adjustment should be evaluated not only for its effect on the target luminosity range but also for its impact on adjacent ranges. This interdependence makes HDR Wheels more complex to master than LOG Wheels but provides greater flexibility when needed. The video tutorial demonstrates HDR Wheels being used to recover shadow detail in overexposed footage without affecting properly exposed areas.
Conclusions
The various Color Wheels available in DaVinci Resolve each serve distinct purposes within a professional color grading workflow. Understanding when and how to use each type is essential for efficient, high-quality color correction.
Primary Color Wheels should be learned thoroughly, as they represent a fundamental tool that persists across virtually all professional color grading software. They excel at fixing exposure and creating rough looks that can later be refined with more advanced tools. Their forgiving nature makes them ideal for broad adjustments and establishing the foundation of a grade.
LOG Wheels serve best as a tool for minor adjustments and refinement. They provide precise control over specific luminosity ranges without affecting the rest of the image, making them valuable for final touches such as capping highlights or adjusting black levels. However, their segmented nature means they should be used carefully to avoid creating unnatural transitions.
HDR Wheels occupy a middle ground, offering multiple control points that affect specific luminosity ranges while still interacting with adjacent areas. They prove particularly useful for recovering detail in shadows or highlights and for working within HDR workflows, though they remain valuable even in SDR projects when nuanced contrast control is needed.
A key principle for efficient color grading is to perform most corrections using primary nodes—nodes that affect the entire image. This approach makes it significantly easier to copy and paste grades across multiple clips in a project, as primary corrections generally translate well between shots with similar characteristics. While secondary corrections and selective adjustments have their place, building a strong foundation with primary corrections streamlines the entire grading process.
Mastering these tools requires practice and experimentation. Rather than trying to learn every available tool superficially, focus on understanding Color Wheels deeply and integrating them into a consistent workflow. As proficiency develops, the efficiency and quality of color grading work will improve substantially, often allowing entire projects to be corrected using primarily these fundamental tools.
