Light and Color ​

Physics of light waves and physiology of the eye Unit 1 : Light, Sun, Electromagnetic Waves:

  • Module goals and objectives.
  • Electromagnetic waves and electromagnetic radiation.
  • Electromagnetic spectrum and its main ranges.
  • Nature of light: structure of the Sun, solar radiation spectrum, Earth's atmospheric absorption spectrum. Unit 2 : Color, Physiology of Perception:
  • Definition and composition of color.
  • Structure of the human visual system (cornea, vitreous body, lens, fundus).
  • Fundus: rods and cones, three types of cones.
  • Brain interpretation of visual signals and color perception. Unit 3 : Color Models and Working with Them:
  • Definition and purpose of color models.
  • Subtractive color models (RYB, CMYK) and additive color models (RGB, HSL).
  • HSL model as the basis of the Chromatone system.
  • Working with color models in the application. Unit 4 : Color Wheel, Primary and Secondary Colors:
  • Color wheel as a combination of color models (RYB CMYK).
  • Primary colors: red, orange, yellow, lime, green, mint, blue, azure, violet, fuchsia, crimson.
