Imagine that you have a green lightbulb in a darker will using a colour light, appeared to change the colour of the Objects in the room
If I have a green lightbulb in a darker room, using a color light, it would indeed appear to change the color of objects in the room. The green light emitted by the bulb would interact with the objects in the room, altering their perceived colors based on how they reflect and absorb different wavelengths of light.
For example, if there is a white object in the room, it normally appears white because it reflects all colors of light, including red, green, and blue. However, when the green light from the bulb shines on it, the object will primarily reflect and absorb green light. As a result, the white object may now appear to have a greenish tint.
Similarly, objects with colors that strongly reflect or absorb green light will appear differently under the green illumination. For example, a red object might look darker or even blackish under the green light since it absorbs most of the green light rather than reflecting it.
It is important to note that the perceived color change occurs due to the interaction of the green light with the objects' pigments or dyes. The actual color of the objects remains the same, but our perception of their colors is influenced by the lighting conditions.
