Colors are everywhere and there are an infinite number of shades. What is this phenomenon? What do they represent?
What is color and how do we see it?
Light is an electromagnetic wave (like a radio wave) and "its color" depends on its wavelength.
Its size gives it its "color": when the wavelengths are short - around 380 nm - we perceive them as blue-violet and when they are longer - around 700 nm - we perceive them as red. The set of visible waves is called the spectrum of visible light. There are waves that are too long or too short to be seen, such as ultraviolet. A spectrum of sunlight is obtained if it is passed through water droplets. This creates a rainbow where we perceive all the colors below.

The eye is a complex organ that has evolved over centuries. It is what allows us to see the world in color and to perceive thousands of shades. We visualize colors thanks to the cones in our eyes. These cones only perceive red, blue, and green. It is by mixing these three colors that the brain is able to "create," reconstruct, and therefore perceive all the "other" colors.
That's why an RGB color model was invented. Thus, screens have Red-Green-Blue or RGB pixels. They mimic the functioning of the human eye thanks to three types of pixels.
In 1930, the International Commission on Illumination discovered that human beings with the finest visual acuity are able to distinguish up to 200 shades per color!
What do colors say about you?
Colors have a strong power of mental association. In the collective unconscious and imagination, colors awaken emotions. They have symbolism. Here are a few:
- Blue: serenity, calm, and inspiration
- Red: passion, energy, and danger

And you, what color best represents you?
Trendy colors
Each year has an official color. Since 2000, Pantone, a color chart company, determines the color of the year with the aim of inspiring creative circles and fashion.
In 2019, the color chosen by Pantone is the color of happiness: it is Living Coral, a very subtle orange-pink coral.

Coral can be combined with dark red tones as well as deep violet, mauve, plum or even aubergine. The whole serves to bring out the coral color. Other color combinations are possible, such as with pink, red, yellow and orange. These combinations are a little riskier, but the result can be very effective.
