what would happen if one red light one blue light and one green light was shined on a red jecket

If a red light, blue light, and green light were shined on a red jacket, the different colored lights would interact with the fabric in different ways.

The red light would be absorbed by the red fabric, causing it to appear brighter and more vivid. The blue light would likely be absorbed as well, but could create a slightly different shade of red due to the interaction between the two colors. The green light, being the complementary color of red, would create a contrast with the red fabric, potentially making it appear darker or more muted in color.

Overall, the combination of all three colored lights would likely create a visually interesting effect on the red jacket, with the red light dominating and the other colors adding nuances and variations to the color of the fabric.
