Color combinations

complementary colors and combinations

According to the physical analysis, the colors can be distinguished in elementary or primary (yellow, red, blue) and compounds or secondary (green, purple, orange), which derive from the combination of two primaries.

The extreme terms of the color register are white and black.

The physics of colors

In physics more than color we should talk about color sensation.

In fact, every electromagnetic radiation of wavelength between 0.8 and 0.4 micron gives rise to a sensation of color.

The color of a certain body depends on the spectral distribution of the incident and reflected light. If a body is struck by white light and reflects only the green component, it will appear green. A body that absorbs all the components will appear black.

In addition to the pure physical issue, on the other hand, there is also physiology, that is the reception of color by the human eye , and the consequent reading that makes the brain. For this reason, colors are as important as color combinations.

See the examples below and record the different impressions that derive from these pairs of rectangles. The dimensions are the same for everyone, but so do not seem at first glance. The colors are always the same, but note that there are differences between one use and another.
