Drawing by Marguerite Smith, Saskatoon Color Color occurs when light in different wavelengths strikes our eyes. Objects have no color of their own, only the ability to reflect a certain wavelength of light back to our eyes. As you know, color can vary in differing circumstances. For example, grass can appear gray in the morning or evening or bright green at noon. Colors appear different depending on whether you view them under incandescent, florescent or natural sunlight.
Colors also change according to their surroundings.
You can see this by looking at the color squares below - the reddish outline box is the same color in all the examples. Properties of Color Hue Hue refers to the color itself. Each different hue is a different reflected wavelength of light. White light occurs when all the wavelengths are reflected back to your eye, and black light occurs when no light is reflected to your eye. This is the physics of light.
