RH Color Bracket DCTL

RH Color Bracket V1 DCTL – Precision Color Isolation & Density Tool

Surgical color separation with mathematically perfect isolation.

If you have worked as a Colorist/DI at any capacity, you know that isolating specific hues cleanly—without breaking the image or introducing noise—is one of the hardest challenges in grading. Standard qualifiers often fail at the edges, creating chatter, artifacts, or harsh transitions. Hue vs Sat/Lum curves are powerful but lack the ability to target specific volumetric "wedges" of the color space precisely.

RH Color Bracket gives colorists a mathematical approach to color selection. Instead of "picking" a color, you define a precise geometric bracket around primary hues using a dropdown menu, eliminating guesswork. It allows you to apply density, saturation, and even force a uniform hue to isolated vectors with zero artifacting and perfect, smooth falloff.

Key Features

• ✔ Uniform Hue Homogenization A game-changer for skin tones and split toning. When enabled, this forces every pixel in your selection to a single, identical hue value. Perfect for unifying blotchy skin or creating architecturally precise color schemes.

• ✔ Asymmetric Full-Range Coverage Our unique asymmetric slider design (210°/150°) ensures you can capture the complete luminance and saturation range of any hue. Whether targeting a sliver of Red or the entire cool spectrum, you never run out of "reach" or create gaps in the color wheel.

• ✔ 6-Vector Visual Bracketing Instantly target primary and secondary hues (Red, Yellow, Green, Cyan, Blue, Magenta) via a clear dropdown menu. No more "guessing" where the center vector lies.

• ✔ Outer Softness Logic Unlike standard tools that "eat" into your selection, our unique Outer Softness engine extends outwards from your core selection, ensuring your target color remains 100% solid while fading smoothly into neighbors.

• ✔ Subtractive Density Engine Apply filmic density (richness) to your isolated color. This isn't just darkening; it subtracts luminance based on saturation, mimicking subtractive film stock behavior.

Controls Overview

• CENTER HUE (Dropdown) Select your target vector instantly: Red, Yellow, Green, Cyan, Blue, or Magenta. Visual confirmation ensures you start from a mathematically perfect center every time.

• UNIFORM HUE & VAL The "Secret Weapon." Check this box to unify the hue of your entire selection. Adjust the Uniform Hue Val slider to dial in the exact target shade—invaluable for fixing skin tone variances or locking in a specific creative look.

• LEFT / RIGHT WIDTH Asymmetric controls calibrated to utilize the full range of each hue. Define exactly how far your selection extends toward neighboring colors without worrying about overlap or "dead zones."

• SOFTEN EDGES Feather the selection outward from the core width. This guarantees your primary color stays fully selected while blending seamlessly into the rest of the image.

• DENSITY Adds "weight" to the selected color by effectively lowering luminance in highly saturated areas, creating deep, rich, film-like colors.

Installation

Place RH_Color_Bracket.dctl in your DaVinci Resolve DCTL folder

Copy RH_Color_Bracket.dctl to your Resolve DCTL folder:

• macOS: ~/Library/Application Support/Blackmagic Design/DaVinci Resolve/LUT/

• Windows: %AppData%\Blackmagic Design\DaVinci Resolve\Support\LUT\

• Linux: ~/.local/share/DaVinciResolve/LUT/

Restart DaVinci Resolve In the Color page, find it under Effects Library > DCTL (or right-click a node and select DCTL).

Recommended Workflow

1. Select your Center Hue (e.g., Red for skin).

2. Enable Show Mask to visualize exactly what is being selected.

3. Adjust Left/Right Width to encompass the specific range of hues you need.

4. Optional: Enable Uniform Hue if you need to homogenize skin tones or force a specific split-tone look.

5. Dial in Density and Saturation to shape the color's character.

6. Disable Show Mask before output.

RH Color Bracket transforms color selection from a guessing game into an exact science—giving you absolute control over the palette of your image.
