You can create different light colors by mixing different primary colors of light.
Mixing Primary Light Colors
The primary colors of light are red, green, and blue. By combining these colors in different proportions, you can produce a wide spectrum of colors.
- Red and Blue: Mixing red and blue light creates a pink or magenta color, as noted in the video reference.
- Green and Blue: Combining green and blue light results in a turquoise or cyan color.
- Red, Green and Blue: When red, green and blue light are mixed in equal proportions, white light is created.
Color Addition
Unlike mixing paint, which is subtractive, mixing light colors is additive. This means that when you combine different colors of light, the resulting color becomes brighter. Here's a breakdown:
- Red + Green = Yellow
- Red + Blue = Magenta (Pink)
- Green + Blue = Cyan (Turquoise)
- Red + Green + Blue = White
Practical Applications
The principle of mixing light colors is used in various technologies:
- Television Screens and Monitors: These devices use tiny red, green, and blue light sources (pixels) to create all the colors you see.
- Stage Lighting: Theater lighting uses colored lights to create different moods and effects.
- LEDs: Light emitting diodes are available in various colors, and multiple colored LEDs can be combined to produce different shades.
Table of Light Color Mixing
| Color 1 | Color 2 | Resulting Color |
|---|---|---|
| Red | Green | Yellow |
| Red | Blue | Magenta (Pink) |
| Green | Blue | Cyan (Turquoise) |
| Red | Green | White |
| Red | Blue | White |
| Green | Blue | White |
| Red | Green | White |
| Red | Green | White |
| Green | Blue | White |
By understanding how to mix red, green, and blue light, you can generate a vast range of colors, as demonstrated in the YouTube video showing the combination of red, blue, and green lights.
