The first time I integrated an image of the Eagle Nebula into an immersive installation project for a Parisian boutique hotel, the artistic director froze in front of the famous Pillars of Creation. “These colors... are they real?” he asked me. I smiled. I’ve been hearing that question for fifteen years as an art director specializing in scientific imagery for high-end spaces.
Here's what the Hubble Colors bring us: they reveal the invisible by translating imperceptible wavelengths into striking visual palettes, they have created an aesthetic language that has influenced contemporary design for three decades, and they transform cold science into accessible visual poetry. But this stunning beauty hides a fascinating secret: these colors do not exist as you see them.
The problem? We live in a world saturated with spectacular space images without ever understanding what makes them so hypnotic. We decorate our interiors with these cosmic visuals, we share them, we admire them, but we completely ignore the creative process behind each hue, each gradient, each chromatic explosion. This lack of knowledge deprives us of a deeper understanding of what we are contemplating.
Rest assured: understanding the truth behind Hubble images does not diminish their magic at all. On the contrary. Discovering how these colors are created, assigned, choreographed by artist-scientists reveals an even more fascinating dimension: that of a collaboration between technology, science and aesthetic sense which has literally invented a new visual language.
I invite you on a journey behind the scenes of this space aesthetics that has redefined our relationship with the cosmos and influenced entire areas of contemporary design.
The great cosmic misunderstanding: what Hubble really sees
When the Hubble Space Telescope captures an image, it doesn't work like your camera. It does not record “true” colors because it does not photograph in only the visible spectrum. Hubble collects light data through ultra-specific filters that isolate precise wavelengths: infrared, ultraviolet, X-rays, and yes, also some portions of the visible spectrum.
Each observation generates files in grayscale levels, maps of light intensity that look more like x-rays than the brilliant splendors we know. Imagine: the majestic Orion Nebula, before processing, appears as a series of gray patches of varying intensity. No electric turquoise, no deep magenta, no incandescent gold.
The raw reality? If you could float in front of these nebulae with your human eyes, you would mainly see... gray, pale brown, perhaps some dull reds. Our eyes are simply not equipped to perceive the spectral richness of these cosmic phenomena. This is where what I call chromatic translation comes into play.
The alchemy of colors: how an iconic image is born
At the Space Telescope Science Institute in Baltimore, a team combines scientists and image processing specialists. Their mission? To transform these raw data into visuals that tell a scientific story while captivating the eye. This process follows a precise methodology but leaves substantial room for artistic sensibility.
First step: color assignment. Each filter used by Hubble receives a conventional color. The filter capturing ionized hydrogen (H-alpha) is often assigned red or orange. Double ionized oxygen (OIII) typically becomes blue or cyan. Ionized sulfur adopts golden or deep red hues.
This Hubble palette is not random: it is based on the technique called "Hubble Palette" or SHO (Sulfur, Hydrogen, Oxygen) palette, popularized in the 1990s. But here's a secret few know: these assignments are aesthetic choices as much as scientific ones. Teams could have decided that oxygen would be green and sulfur violet. The image would have been just as scientifically valid, but radically different visually.
The palette that changed our imagination
Take the famous Pillars of Creation. In the 1995 version, the tones oscillate between emerald greens, copper golds and dark reds. This combination is not "false": it faithfully represents the distribution of chemical elements. But it is constructed, choreographed to maximize scientific contrast, readability and emotional impact.
In 2015, a new version reveals these same pillars with a different palette: more blues, more subtle nuances. Same object, similar data, visually distinct result. This demonstrates that these space images are interpretations, artistic translations of physical realities imperceptible to the naked eye.

When science meets design: the birth of an aesthetic
What has fascinated me since my beginnings in integrating space imagery into residential and commercial spaces is how this Hubble aesthetic has migrated beyond the scientific community to profoundly influence contemporary design.
Observe the trends of the last fifteen years: cosmic gradients dominate the visual identity of tech startups, "galaxy" palettes invade fashion and decoration, nebulous effects structure the aesthetics of video games and science fiction cinema. This influence is not accidental. The Hubble colors have created a new visual vocabulary associated with innovation, mystery, scientific elegance.
For my interior design projects, I frequently use large-format prints of nebulae or galaxies. Their impact goes beyond simple decoration: these images bring a contemplative depth, a window to infinity that transforms the perception of space. A living room becomes an observatory, a bedroom becomes a metaphorical spaceship.
The color codes of the cosmos
Modern space aesthetics are based on a few chromatic principles that Hubble has popularized: extreme complementary contrasts (electric blue against incandescent orange), multi-directional gradients that suggest three-dimensionality, the use of deep black as a structuring element, and the integration of bright points (stars) as rhythmic accents.
These codes are now found everywhere: in user interfaces seeking to evoke advanced technology, in packaging for high-end products wanting to suggest innovation, in interior architecture seeking to create immersive and contemplative atmospheres.
False colors, true science: fidelity through betrayal
So, are these Hubble colors lies? This is where the fascinating paradox lies: these "false" images reveal truths that our eyes could never perceive. They are scientifically authentic while being visually constructed.
Each shade codes a chemical, thermal or energy information. The intense blue of a region indicates the massive presence of ionized oxygen. Reddish areas signal burning hydrogen. Golden structures reveal concentrations of sulfur. These chromatic maps allow astrophysicists to understand at a glance the composition, temperature, movements and age of the observed structures.
Without this colored translation, this information would remain buried in tables of numerical data. The "false" color thus becomes the tool that makes science accessible, understandable, shareable. It is a betrayal that tells the truth, a fiction that reveals reality.
The emotional power of visualization
In my collaborations with architects and designers, I have observed that Hubble’s spatial images evoke exceptionally strong emotional reactions. Unlike terrestrial photographs, even spectacular ones, these cosmic visuals engage a different form of contemplation: more abstract, more meditative, almost spiritual.
This emotional resonance is not accidental. Hubble's image processing teams have gradually refined their approach, integrating principles of composition from classical painting, art photography, and cinema. They create visual artworks that respect the balance of masses, visual rhythm, and hierarchy of elements.

The visual legacy of three decades of exploration
Since its launch in 1990, Hubble has produced over a million observations and tens of thousands of processed images. Among them, a few dozen have become truly iconic: the Pillars of Creation, the Horsehead Nebula, the Sombrero Galaxy, the Hubble Deep Field.
These images have transcended their scientific function to become cultural icons. They appear on album covers, in films, on textiles, in public spaces. They have shaped the contemporary collective imagination of the cosmos more effectively than any scientific text.
For new generations, these space colors literally define what the « universe » looks like. It doesn't matter how they are constructed: they have become our shared visual reference for the distant cosmos. This is a fascinating case where representation has created perceptual reality.
Beyond Hubble: the continuing evolution
The James Webb Space Telescope, Hubble’s successor launched in 2021, continues this tradition of chromatic translation with even greater capabilities. Its images, captured primarily in the invisible infrared, undergo a similar process of color assignment. But teams have had to develop new palettes, creating an evolution of space aesthetics.
This continuity demonstrates that we are not dealing with a simple technique, but with a true visual language that will continue to evolve and influence our visual culture for decades to come.

Taming infinity: integrating the space aesthetic into your home
Imagine yourself every morning facing a window onto infinity. A large format of the Orion Nebula above your sofa, the Pillars of Creation structuring your workspace, a spiral galaxy bringing depth and mystery to your bedroom. These cosmic images are not just decorations: they change the perception of space, create visual vanishing points that enlarge rooms, bring a rare contemplative dimension to our contemporary interiors.
Start by choosing an image that resonates with you, not only aesthetically but emotionally. Integrate it as a work of art in its own right, giving it the space and lighting it deserves. Let these Hubble colors, constructed yet authentic, false yet true, remind you every day that beauty can be born from science, that art can reveal the invisible, and that sometimes, the most beautiful truths require a little creative translation.
Frequently asked questions about Hubble colors
Are Hubble images completely invented?
No, absolutely not. Hubble colors are faithful translations of real scientific data. Each shade corresponds to a specific chemical element, temperature or particular wavelength. What is “constructed” is the choice of which visible color will represent such invisible wavelength. For example, ionized oxygen emits in the ultraviolet that we cannot see, so scientists assign it a visible color like blue. The scientific information remains perfectly accurate: only the color code changes. It's like translating a Japanese text into French: the meaning remains identical, only the language changes. These images reveal truths that our eyes alone could never perceive.
Why not show the true colors that the human eye would see?
Because it would be scientifically less informative and visually disappointing. If you could float in front of the Orion Nebula, you would mainly see gray, pale brown, and perhaps some dull reds. Our human eyes have limited sensitivity: they only capture a tiny portion of the electromagnetic spectrum and need a lot of light to distinguish colors. Nebulae are too diffuse to effectively stimulate our retinal cones. The Hubble false colors therefore do not betray reality: they reveal it more completely than our eyes ever could. They transform the invisible into the visible, allowing both scientists to analyze phenomena and the public to marvel at their hidden beauty.
Does this space aesthetic really influence contemporary design?
Absolutely, and profoundly. Since the 2000s, the Hubble aesthetic has permeated virtually every field of design. The interfaces of technological applications use these cosmic gradients to evoke innovation. Fashion regularly incorporates « galaxy » patterns directly inspired by these images. High-end interior architecture uses these visuals to create contemplative spaces. Science fiction cinema draws inspiration from them for its color palettes. This influence is not superficial: Hubble colors have created a visual vocabulary associated with advanced technology, elegant mystery, and contemplative depth. They have literally redefined our visual imagination of the cosmos and, by extension, of everything that evokes the future, exploration, and the unknown.
