Color Vision

The title of the Project: Color vision

Purpose of the virtual laboratory work:

  • to demonstrate how different colors of light are perceived by the human eye
  • to explain the role of wavelengths and how specific colors are absorbed by the eye.
  • to showcase the concept of primary colors and how they combine to create other colors.

Practical part

This virtual simulation helps you understand how different colored lights appear to human eyes.

1. Turn on the simulation. You will be given a choice of two modes: Single Bulb and RGB Bulbs.

2.Observe a human face with thought bubbles, representing someone’s perception of light.

On the right, find a flashlight with different bulb and filter colors.

Single Bulb Screen

3. Choose a single bulb color (e.g., red). See how the person perceives only that color. Change the bulb to yellow or blue, and witness the shift in their perception.

4. Turn on “photon view” to see all the invisible lights the person absorbs.

5. Shine white light. Notice both the white light and the person perceiving it as white. Now activate “photon view” to reveal the secret: a mixture of all colors combined by our brain to create white.

6. Apply a filter to white light. Watch as the person sees only the filtered color (e.g., yellow). “Photon view” shows all colors present, but only yellow reaches the eye.

RGB Bulb Screen

7. Now switch to the RGB bulb screen. There are three primary colors of light: red, green and blue. These colors form the basis of the RGB color model, which is used to create images on TV or computer monitors. Its name is an abbreviation created from the first letters of the colors (Red, Green, Blue). When combined they create countless other colors. Screens use these colors in different proportions to display different shades.

8. See how combining primary colors produces new ones:

Red + Green = Yellow

Red + Blue = Magenta

Green + Blue = Cyan

Red + Green + Blue = White

9.Remember: This simulation demonstrates how our brains interpret the light we see, creating the vibrant world of colors we experience.

Conclusion:

The virtual lab provided an interactive and engaging way to learn about the science behind color vision and light manipulation. By combining visual elements, clear explanations, and hands-on exploration, it deepened the student’s understanding of these concepts.
