The **Color Input Node** (`ColorNode`) provides an interactive chromatic wheel interface directly on the node graph canvas, streaming standardized color signals to downstream fixtures and math processors.

## 🎨 Color Architecture & Abstraction

Unilighter uses a universal internal color representation. When a `Color` signal is wired to a [Device Node](https://unilighter.cc/info/for-ai/docs/node-graphs/device.md), the console automatically translates the coordinates to the physical fixture's native emitter configuration:
- **RGB / RGBW / RGBAW-UV**: Calculates optimal white and amber emitter blending.
- **CMY Subtractive Mixing**: Automatically inverts RGB signals into subtractive Cyan, Magenta, and Yellow flag positions.
- **Indexed Color Wheels**: Selects the closest matching physical gel filter on motorized color wheel fixtures.

## 🔌 Socket Outputs Reference

| Output Socket | Data Type | Range | Description |
| :--- | :--- | :--- | :--- |
| **Color** | `Color` | Hex / RGB / HSL | Standardized color stream compatible with all color inputs across the graph. |
| **R / G / B** | `Number` | `0.0 – 1.0` | Individual Red, Green, and Blue component intensity values. |
| **H / S / L** | `Number` | `0.0 – 1.0` | Hue angle (`0.0–1.0` mapped to 0–360°), Saturation, and Luminance channels. |

- **Dynamic Hue Modulation**: Use a [Math Node](https://unilighter.cc/info/for-ai/docs/node-graphs/math.md) to add an [Oscillator](https://unilighter.cc/info/for-ai/docs/node-graphs/oscillator.md) output to the `H` socket for continuous slow rainbow color drifting.
