Primary Colors of Light

  1. Primary colors of light are red, green, and blue (RGB).
  2. These colors are called primary because they cannot be produced by combining other colors of light.
  3. When combined in equal proportions, they produce white light.
  4. Primary colors are used in devices like TVs, monitors, and projectors for color mixing.
  5. The RGB model is based on the additive color theory.

Secondary Colors of Light

  1. Secondary colors are formed by combining two primary colors.
  2. Red + Green = Yellow.
  3. Green + Blue = Cyan.
  4. Blue + Red = Magenta.
  5. The secondary colors are important in understanding the additive color mixing process.

Color Wheel and Additive Mixing

  1. The color wheel illustrates the relationship between primary and secondary colors.
  2. Combining all three primary colors (red, green, blue) in equal intensity produces white.
  3. Combining one primary and one secondary color produces intermediate colors.
  4. Additive mixing is used in technologies like theater lighting and visual displays.

Difference Between Additive and Subtractive Colors

  1. The additive color system involves light, where colors are created by adding light of different wavelengths.
  2. The subtractive color system involves pigments or dyes, where colors are created by subtracting certain wavelengths of light.
  3. Primary colors in the subtractive system are cyan, magenta, and yellow (CMY).
  4. In the additive system, adding all colors produces white; in the subtractive system, it produces black.

Applications of Color Theory

  1. The RGB model is widely used in screen displays and digital media.
  2. Understanding primary and secondary colors is crucial for designing optical instruments and visual effects.
  3. Color mixing principles are applied in lighting design, photography, and cinematography.
  4. Primary and secondary color theory is fundamental in the study of vision and perception.
  5. Revise the primary colors (red, green, blue) and their combinations.
  6. Understand the formation of secondary colors (yellow, cyan, magenta).
  7. Learn the difference between additive and subtractive color mixing.
  8. Know practical applications like television displays and theater lighting.
  9. Memorize examples of how color mixing impacts everyday technologies.
