• Under Lighting: Less common, this technique can evoke a sense of unease or horror, as it illuminates from below.

3. Color Theory in Lighting

Color can profoundly impact emotional responses. Understanding color theory is key for any lighting designer. Some aspects to consider are:

• Color Temperature: Measured in Kelvin, different temperatures can alter the mood. Cooler lights (6000K-7500K) suggest daylight, while warmer (2000K-3000K) evoke sunset or candlelight.
• Color Filters: Use gels or LED color mixing to create specific atmospheres. Blending different colored lights can yield powerful effects.
• Cues and Mood Changes: Transitioning colors throughout a performance can mimic emotional arcs or shifts, providing visual storytelling.

4. The Use of Special Effects

Incorporating special effects in lighting can create unique and immersive experiences:

• Gobos: Stencils placed in front of lights to project patterns or shapes, adding texture to backgrounds.
• Strobe Lights: Create a sense of urgency and excitement but should be used sparingly, as they can be disorienting.
• Chase and Build Effects: Using a sequence of lighting cues can create dynamic movement and energy.
