The word tone can have several applications because its meaning is broad enough to be used in a diverse way. The notion of tone always implies the presence of a scale, whether of sounds, colors, etc., in which the tone is one of the links or parts that make up the whole. Thus, a color scale can have several shades that will be characterized by elements or particular features that are distinguishable from each other. It goes without saying that since nature is not ordered in a systematic way, the notion of tone or scale is an invention of the human being to classify and organize the information we receive from the environment.
One of the most common ways in which the word tone is used is that which has to do with colors. This is related to the idea of a color scale in which there are primary colors (red, blue, and yellow) and secondary colors (purple, orange, and green) that are solid. Between each of these solid colors we find at least one tone that is a combination of both colors and that unites them in a more progressive way. The greater the presence of shades we find between one color and another (for example, between red and yellow), we must speak of a greater or lesser presence of light since it is, in short, the one that gives rise to the various shades. Thus, a red with greater light than another will approach orange and then this will approach yellow.
Another of the forms used of the term tone is the one that has to do with sounds. The tone of voice or volume of some sounds is variable and can also be classified in more or less specific scales that go from very low and quiet sounds to high and very stunned sounds. The intermediate tones between the lowest, an acceptable volume and the highest are numerous and allow us to adapt our hearing to different types of sounds.
