Color is a visual experience, a sensory impression that we receive through the eyes, independent of its coloring matter.
The world around us is shown to us in color. The things we see differ not only in their shape and size, but also in their color. Every time we observe nature or an urban landscape we can appreciate the amount of colors that are around us thanks to the light that falls on the objects.
The concept of color varies according to the field that is used; From the physical point of view, color is a physical property of the light emitted by objects and substances. In chemistry they describe it by means of a formula that represents a reaction of elements.
Psychology and philosophy show color as a carrier of expression, effectiveness, sensation, of a certain symbolism and character, possessing its own language and meaning. Color as an influencer in the human being, when it dominates the environment. For example, being in yellow gives a serene and cheerful mood, it is a positive influence. In the language of the plastic arts, color is a primary qualifier for objects, in some works and artistic movements color stands as the protagonist.
Color is said to derive from the decomposition of white light from the sun, or from an artificial light source or source. The appearance of these colors is always visual, and it will vary depending on the nature of the light rays and the way they are reflected.
The white color of some bodies is due to the reflection of all the rays of the visible spectrum. In the decomposition of white light, the seven spectral colors are seen: red, orange, yellow, green, blue, indigo and violet. The black color, resulting from the absence of any luminous impression, is in opposition to the white color.
We also have the pigment color or matter color, which is conceived as the ability of bodies to absorb a certain portion of light rays and reflect only the wavelength that corresponds to itself. For example; the apple absorbs all the colors contained in white light, but reflects only the portion of red rays. Pigments of organic origin have their origin in the vegetable or animal kingdom, and inorganic pigments are the colors that are derived from minerals (earth colors).
Color has three distinct dimensions: tone, also called tint or hue, is its own color quality; the value is the degree of luminosity of the color between the terms of light and darkness; and intensity or saturation; It is the degree of purity of the color that a surface can reflect.
