Answer 1

Here’s a sample data table based on common observations you might make when adjusting light colors:

| Light Color | Perceived Color |
|---------------------|------------------------|
| Just red | Red |
| Just green | Green |
| Just blue | Blue |
| Red and green | Yellow |
| Red and blue | Magenta |
| Green and blue | Cyan |
| Red, green, and blue| White |

If you don’t move the sliders all the way up, how does it change what you perceive?
- When the sliders are not moved all the way up, the intensity of the light is reduced, which can lead to the colors appearing less saturated or even dimmer. For instance, a lower slider position may result in a more pastel version of a color or blend colors in unexpected ways, reducing the overall brightness and altering the perceived hue.

Summarize what you have learned from this investigation.
- This investigation demonstrates the additive color mixing principle where different colors of light combine to create various perceived colors. When mixing red, green, and blue light at full intensity, the result is white light, indicating that these colors can be combined effectively. My observations highlight how varying the intensity of each primary color affects the final perceived color, illustrating the relationships between them and how our visual system interprets these combinations.
