The world of colors has always fascinated humanity, but what many don't know is that pink is a real exception in physics. While other shades have their associated wavelengths, pink remains absent from this spectrum.
Physicist and doctoral student in astrophysics Roberta Duarte explains the intriguing reason behind this peculiarity in an illuminating thread from the twitter.

This post went viral recently after the premiere of the movie 'Barbie' in theaters, in which the color pink is one of the protagonists. Understand more below!
To understand why pink doesn't exist in physics, it's important to understand how science sees colors.
According to the expert, colors are actually wavelengths that light has, and this electromagnetic spectrum ranges from gamma rays to radio waves.
However, the human beingsthey can only perceive a band, known as the visible spectrum, which covers 400 to 700 nanometers (nm).

In this visible spectrum, humans have the ability to identify colors based on the different wavelengths that light has.
For example, the Sun emits most of its photons in the green part of the spectrum, which influences both the evolution of humans, such as the vision of other animals, including nocturnal animals.
However, it is in this explanation that the absence of pink becomes evident. There is no specific wavelength that is associated with the color pink in the visible spectrum.
While red, blue and green all have different wavelengths, pink simply doesn't fit into that category.
Roberta Duarte made some interesting remarks so that we can better understand the phenomenon of this color.
If the two ends of the visible spectrum (red and violet) came together in a circle, pink would emerge as a result of the combination. However, the visible spectrum is linear, which makes it impossible for this color to exist in physics.

Although pink is an element present in other areas of knowledge, such as Neuroscience, its absence in Physics is intriguing and reveals a fascinating mystery about the nature of light and human vision.
The knowledge shared by physicist Roberta Duarte leads us to appreciate even more the complexity and diversity of colors in our world.
In any case, pink may not even exist in physics, but it continues to enchant and inspire everyone, becoming a unique and fascinating expression in various fields of culture and human knowledge.
