How could you use the spotlights at a play to make the yellow clothes of the performers suddenly change to black?
Shine the complementary color of yellow on the clothes. Look at the color wheel. The color diametrically opposed to yellow will be the complementary color of yellow.
shine a blue light on the yellow clothes

To make the yellow clothes of the performers suddenly change to black using spotlights, you can utilize a lighting technique called "masking" or "shadowing." Here's how you can achieve this effect:
1. Prepare the lighting setup: Set up two spotlights with different color filters, one with a yellow filter and the other with a black filter. Position them in such a way that they will precisely illuminate the performers on stage.
2. Start with yellow illumination: Initially, illuminate the performers with the spotlight having the yellow filter. This will make their yellow clothes appear vibrant and prominent on stage.
3. Coordinate the transition: As the moment to change the clothes from yellow to black approaches, gradually fade out the yellow spotlight while simultaneously fading in the black spotlight. This can be done by adjusting the intensity of the spotlights or by using a lighting console to control the transition smoothly.
4. Casting shadows: As the black spotlight becomes dominant, position it to cast shadows on the performers. Shadows can be created by placing objects or cutouts in front of the spotlight to partially block the light, creating a shadow effect on the yellow clothes. This will give the illusion of the performers' clothes changing from yellow to black.
5. Fine-tuning and timing: Experiment with the intensity, angle, and positioning of the black spotlight to achieve the desired effect. The timing of the transition is crucial, so make sure it aligns with the music, choreography, or any other cues in the play.
By carefully orchestrating the fading of the yellow spotlight, the gradual introduction of the black spotlight, and the strategic placement of shadows, you can create the illusion of the performers' yellow clothes turning black using spotlights in a play.
