Chapter 1 Understanding Magenta

Magenta is a color many of us are familiar with; it exists as a blend of purple and red hues, resembling a pinkish-purple shade. However, this notion comes with a caveat: within the light spectrum, the colors that fall between purple and red actually include yellow, green, blue, orange, and so forth. Magenta, instead, appears on the color wheel, which visually represents how colors transition into one another. Red and purple occupy the two ends of this spectrum, seamlessly merging into magenta on the color wheel.

So, if magenta isn’t part of the light spectrum, how can we perceive it? The answer lies in how our brains interpret colors. Each visible color corresponds to a particular wavelength, and since magenta has no specific wavelength on the spectrum, it is a color our brains construct to fill a perceived gap.

When the brain assesses colors, it tends to average them to produce a coherent result. For instance, combining green and red light yields yellow because the brain averages the wavelengths. In the case of red and purple light, the brain calculates an average wavelength that would typically be green; however, to maintain logical consistency, it synthesizes the two colors and we see magenta.

The perception of colors is fundamentally an averaging process involving three primary colors: red, blue, and green. Humans possess three types of photoreceptors, allowing us to interpret these colors. Consequently, color codes often reflect these primary components—magenta is represented as (255, 0, 255), indicating the specific contributions of each primary color.

In a philosophical sense, one could argue that color doesn’t genuinely exist; it is merely a perception crafted by our brains to differentiate various wavelengths. From an evolutionary perspective, this ability to perceive color would have enhanced survival—enabling better identification of ripe fruits and distinguishing between potential predators.

Various species also exhibit color vision; for example, the Bluebottle Butterfly possesses 15 photoreceptors, far surpassing human capabilities. While humans can discern a wide range of colors, other animals, like bumblebees, can see beyond our visible spectrum, perceiving ultraviolet markings on flowers.

Now, let’s return to the intriguing case of magenta, a color that doesn’t have a place in the light spectrum. Interestingly, magenta is not the sole example of a color that doesn’t exist.

Chapter 2 Imaginary Colors: Exploring the Concept

The first video, "Magenta: The colour that doesn't exist – BBC REEL," delves into the fascinating nature of magenta and how it challenges our understanding of colors.

As we ponder on this, it becomes evident that while magenta is absent from the light spectrum, there are other ways to experience imaginary colors. These are colors that, although they cannot exist permanently, can be perceived momentarily through specific visual exercises. This phenomenon occurs when one focuses on a particular image until the photoreceptors become fatigued. Switching to a contrasting color afterward allows the viewer to perceive these temporary colors.

Among these imaginative colors are Stygian colors, which arise from bright yellow light and subsequently create a dark blue afterimage against a black background. This effect makes the blue appear both distinctly blue and dark against the black, resulting in a unique visual experience.

Self-luminous colors create the illusion of emitting light, even on paper, due to fatigued retinal cells. Here, a green stimulus can produce a bright red afterimage, creating a striking contrast against a white background.

Hyperbolic colors arise in situations where a cyan stimulus yields an oversaturated orange afterimage when viewed alongside an orange block. Notably, if one stares at magenta and then looks at a green leaf, the leaf may appear exceptionally vibrant, similar to the effect with orange.

These so-called "imaginary" colors, though lacking physical wavelengths, pose fascinating questions about our perception of color. As they are not rooted in the spectrum, attempting to assign them a wavelength leads to conventional colors instead. For example, defining a wavelength for hyperbolic orange would yield the standard orange, a blend of more red than green.

In conclusion, the exploration of color and its implications is a captivating journey. It raises profound questions about the true nature of objects in our universe, if color is merely an interpretation of wavelength values. What do our workspaces and the food we consume genuinely look like? Ultimately, our perception might be an elaborate construct, a fleeting idea. Yet, it prompts us to ponder whether there is more to it than meets the eye.

The second video, "Why This Color Doesn't Actually Exist," further expands on the concept of non-existent colors, offering additional insights into the science of color perception.
