Understanding Color - Part 1

Part 1: What is color?



Itten said in The Elements of Colour, “Colour is the children of light”. Leigh Hunt, a 19th century poet wrote, “Colors are the smiles of nature”. Goethe wrote in his Theory of Colour. “ Colours and light it is true stand in the most intimate relation to each other, but we should think of both belonging to nature as a whole, for it is nature as a whole which manifests itself by their means in an especial manner to the sense of sight”. The visual system is not just a conduit for seeing but an interrelated system that communicates and effects us on many levels and links us to nature as a whole. Quantum physicist exert that all matter, human beings included are crystallized light, frozen electromagnetic energy.

Color is what we see. A sensation caused by certain qualities of light as observed by the human eye, a physical process and interpreted by the brain, a psychological process. Visible color exists only in the mind of the viewer. The production of color requires three things- a source of light, an object which illuminates and an eye and brain to perceive the color. (Principles of Color Technology Billmeyer & Salltzman)

The color we see is reflected light. In art and industry color is usually described by the measurement of hue, saturation/chroma and brightness of the reflected light. A white object reflects all wavelengths of light. A black object absorbs. all wavelengths of light. A blue ball reflects the specific wavelengths of the blue we see and absorbs all the other wave lengths. In art and industry a color is usually described by the measurement of hue, saturation/chroma and brightness of the reflected light.

Visible color as light is a form of energy and part of the electromagnetic spectrum. Visible light as perceived by the human eye is between 380 and 750 nanometers. A nanometer is one millionth of a millimeter. Violet is approximately 420 nanometers and red longer than 630 nanometers. From the longest wavelength to the shortest wavelength are wireless communications, induction heat waves, AM radio waves, short-wave band CB, FM radio, television, radar, microwave, infrared, radiant heat, visible red, orange, yellow, green, blue, violet, ultraviolet light, radiation, x-rays, gamma rays and cosmic rays. (Figure 1)



The energy is called electromagnetic because it is related to both electricity and magnetism. The two exist together- you can not have one without the other. When electricity flows there is a magnetic flow around the conductor. When you have magnetism you can produce electricity by moving a conductor through the magnetic field (The Electromagnetic Spectrum- Franklyn Branley).

Einstein said light must be explained by wave but the energy is not distributed evenly along the wave but in bundles or packets that were later called photons. When the frequency of light is increased the photons are more energetic. Ultraviolet photons are more energetic than infrared photons.
