Different lighting instruments offer various methods of color mixing, including color filters (gels), LED color mixing, or rotating color wheels.

• Intensity Control: The intensity of light, also known as brightness, is crucial for creating dramatic effects and focusing attention. Dimmers are used to control the intensity of the light, allowing for gradual transitions and precise adjustments.

• Beam Angle and Distribution: The shape and spread of the light beam are critical factors. Different lenses and reflectors create different beam angles, ranging from narrow spotlights to wide washes. Understanding the beam angle is vital for creating desired lighting effects and covering the stage effectively.

• Light Temperature: Light temperature is measured in Kelvin (K) and indicates the color of the light. Cooler temperatures (e.g., 3200K) produce a warmer, more yellowish light, while hotter temperatures (e.g., 5600K) produce a cooler, more bluish light. This understanding is crucial for balancing lighting across the stage and maintaining a consistent color palette.
