Lee 206: A quarter C.T. orange (1/4 CTO) color correction gel by LEE Filters that warms daylight toward tungsten balance.
Overview
The Lee 206 (full name: 206 Quarter C.T. Orange, commonly known as "1/4 CTO") is a color conversion gel manufactured by the British company LEE Filters. It belongs to the orange CTO (Color Temperature Orange) series, used to lower the color temperature of a light source towards tungsten (warm) light. The "Quarter" (1/4) indicates the weakest of the common CTO gradations – it shifts the color temperature significantly less than 1/2 CTO (Lee 205) or Full CTO (Lee 204).
A typical application is to adjust daylight sources (e.g., HMI, LED in daylight mode, windows) to a warmer lighting mood or to match tungsten sources, without forcing the full conversion jump of a Full CTO gel.
Technical Data
The following values are from the manufacturer's specifications for LEE Filters' 206:
| Property | Value |
|---|---|
| Designation | 206 Quarter C.T. Orange (1/4 CTO) |
| Manufacturer | LEE Filters |
| Function | Conversion Daylight → Warmer (towards Tungsten) |
| Mired Shift | +64 |
| Transmission Y (Tungsten) | 82.6 % |
| Transmission Y (Daylight) | 79.1 % |
The positive Mired shift value (+64) indicates a shift towards warmer light (lower color temperature). LEE offers the 206 in various formats: as sheets (full/half) and as rolls in different widths and core sizes.
On-Set Usage
- Fine-tuning Color Temperature: Warming up a daylight source without achieving the full conversion degree of a 1/2 or Full CTO gel.
- Mixed Lighting Situations: Matching daylight sources to existing tungsten light or to a desired warm ambient mood.
- Gradation with the CTO Family: 1/8 CTO (Lee 223), 1/4 CTO (Lee 206), 1/2 CTO (Lee 205), and Full CTO (Lee 204) can be combined to achieve a gradual effect.
- Mounting: As is customary with gels, place in front of the light source or in a frame/filter holder; maintain sufficient distance from the bulb as the gel is heat-sensitive.
