RH Filmic Colors

🎨 Color Behavior Engine for DaVinci Resolve

Note

RH Filmic Colors is a color behavior tool, not a look preset. It is designed to be used once per shot in a controlled position in the node tree to manage density, saturation, and tonal response.

1. Recommended Node Placement ✅

This tool expects scene-referred / log data. It must be placed correctly to function.

📍 Correct Order

  1. Input Transform / IDT (Log Space)
  2. Primary Balance (Exposure, Temp, Tint)
  3. 🔴 RH Filmic Colors
  4. Creative Look / Secondaries
  5. Output Transform / ODT

⚠️ Pre-DCTL Guidelines

+ ✅ DO: Offset, Exposure, White Balance, Primary Lift/Gamma/Gain
- ❌ AVOID: Heavy Contrast Shaping, Aggressive Saturation, Look LUTs

Why? The cleaner the input, the more predictable the density behavior.

🧩 Parallel Nodes: Keys & Secondaries

If you need isolated adjustments (Keys, Qualifiers): Use Parallel Nodes.

! TIP: Parallel nodes isolate the DCTL from secondary keys, preventing density distortion.

2. Using the Controls 🎛️

🌐 Global Controls

Primary adjustments for the entire image state.

image
Control Function
Global Blend 💧 Master opacity. 0.0 = Passthrough, 1.0 = Full Effect.
Global Sat / Hue 🎨 Applies clean HSV-based saturation and hue shifts to the whole image.
Shape Curve ☁️ Controls the response curve shape. (Enable Show Curve to visualize).
Global Exposure ☀️ Adjusts overall exposure density. Note: Image may clip if pushed too hard.

🔴🟢🔵 Vector Controls (RGB / CMY) 💠🟣🟡

Deep, independent control over specific color vectors using the 6-Vector Engine.

image image
  1. Enable 6-Vector to activate.
  2. Adjust Hue, Saturation, and Density for each of the 6 primary vectors.

Density in this tool is Saturation Weighted. It deepens rich colors without affecting neutral skin tones.

🎞️ Film Density

# Global Density Bias

Controls how light interacts with the image overall. Use this to add "weight" or "thickness" to the image without crushing black levels.

🔀 Split Toning & Unite Options

Show Curve (Analysis)

image

Displays the internal response curve.

Useful for understanding where adjustments are acting.

Split Toning

image

Allows independent control of Shadows 🟦, Mids 🟩, and Highlights 🟥.

Recommended for:

  • Look Development, Split Toning and Controlled Color Shifts

⚫⚪ Unite at White / Black

Defines where color vectors converge at the dynamic range extremes.

Option Effect
Unite at White ⚪ Recommended. Highlights fade to neutral white. Keeps speculars clean.
Unite at Black ⚫ Shadows fade to neutral black. Prevents lifted/tinted blacks.

3. Visual Aids 👁️

Show Zone Masks helps visualize where your Split Toning allows adjustments.

Zone Color Representation
Shadows 🟦 Blue
Midtones 🟩 Green
Highlights 🟥 Red

To visualize the areas falling before after each pivot region. Blue = Shadows 🟦 , Green = MidTones 🟩 , Red = Highlights 🟥

4. Common Mistakes to Avoid 🚫

- ❌ Placing after a Look LUT or Output Transform.
- ❌ Using it as a "Look Generator" (it is a behavior engine).
- ❌ Stacking multiple instances (One per shot is sufficient).
- ❌ Doing heavy secondary keys BEFORE this node.

5. Suggested Workflow Summary 🧭

  1. Set Color Management / IDT.
  2. Balance Exposure / WB.
  3. Add RH Filmic Colors Node.
  4. Adjust Global Response / Density.
  5. Refine Vectors (if needed).
  6. Perform creative grading downstream.

Final Note: Evaluate this tool by how it behaves during grading, not just by how extreme the sliders can be pushed. It is a utility for chromatic preservation.
