Have you ever caught a sunrise and felt everything just settle and go quiet for a second and then wondered how it seems to do that?
There's a reason for that and it's even more fascinating than I thought.
This week I went down a rabbit hole on the science of sunrise colours from a 2023 University of Exeter study on awe, what what warm amber does to your nervous system, and why coral and pink hit differently than anything else in the spectrum.
There's a proven science behind why sunrise colours affect us the way they do and why some of us feel genuinely compelled to be near them and return to them again and again.
Why Sunrises Trigger Awe
In 2023, researchers at the University of Exeter conducted a landmark study showing that sunrises and sunsets reliably trigger one of the most powerful and elusive emotions in human psychology: awe.
Using carefully controlled images shown to more than 2,500 participants, the researchers found that scenes featuring a sunrise were rated dramatically more beautiful than the same scenes photographed under ordinary daylight. And unexpectedly, they also produced significant spikes in feelings of awe.
This matters more than it might sound.
Awe is not a common emotion. It's one of the hardest to elicit in a lab setting harder than joy, calm, or surprise. And yet a sunrise managed to produce it reliably, across thousands of people!
The researchers suspected one reason was the fleeting, unpredictable nature of the event. Sunrise doesn't last. You can't hold it or revisit it. That impermanence and the knowledge that this particular sky, at this particular moment, will never exist again may be part of what makes it feel so significant.
What Awe Actually Does to Us
Dacher Keltner, professor of psychology at UC Berkeley and one of the world's leading researchers on awe, has spent decades studying what this emotion does inside us and the findings are remarkable.
He discovered that awe isn't just a pleasant feeling. It's physically transformative.
It reduces inflammation in the body, calming the kind of chronic immune response linked to depression, anxiety, and heart disease. It activates the vagus nerve (the longest nerve in the autonomic nervous system and connects the brain stem to the heart, lungs, and digestive tract. Think of the vagus nerve as the body's own natural reset switch lowering heart rate, blood pressure, and cortisol. It quiets what Keltner calls the "default self": the part of our brain that narrates, worries, and keeps running lists. And it opens us toward connection to others, to the moment, to something larger than ourselves.
...All of that, in a single sky.
The Colours Themselves: What They Do
The awe is real. And the colours aren't just a side effect or a coincidence. The colours are part of what creates the feeling of awe, not just a pretty backdrop to it.
They are, in a way, what creates it. Each band of colour in a sunrise carries its own psychological frequency, and together they form something our nervous systems are deeply wired to receive. Let's explore what that looks like:
Darks Purples & Blues: The Before
The sky just before dawn is a quiet, deep violet-blue.
These tones are associated with rest and the transition between states. Neither night nor day, neither asleep nor fully awake. Psychologically, deep blue-violet slows the mind and invites a quality of open attention. It's the colour of the in-between, and something about it makes us feel like witnesses to something special.
Soft Pink: The Arrival
As the light builds, the first warmth that enters the sky is what can appear to us as . It's soft and diffuse.
Pink is often underestimated as a colour. But in the context of dawn, it carries an emotional charge that is immediately disarming. It's the colour of something calming, innocent, and new. Studies have consistently linked soft rose tones to feelings of calm, warmth, and emotional safety. In the sky, pink signals "something is beginning" or "something is arriving".
Warm Orange/Amber and Gold: The Opening
Then comes the amber.
This is the colour most of us mean when we talk about a sunrise. That rich, warm gold that floods the horizon and turns everything it touches...luminous.
Amber activates the emotional centres differently from any other colour in the sunrise spectrum. Warm golden tones are associated with vitality, presence, and a sense of aliveness. They signal warmth literally and psychologically.
They are the colour of fire, of honey, of late-afternoon light through glass. At sunrise, that warmth feels even more refreshing and alive.
On a neurological level, warm amber light syncs with your circadian rhythm confirming to your brain that the day has begun. Combined with the serotonin release triggered by morning light hitting the retinas, the appearance of amber on the horizon produces a genuine biochemical uplift and not just an aesthetic one.
Coral and Flamingo Pink: The Moment of Peak
At the height of a sunrise, the colours can often deepen into coral or magenta. A vivid, saturated blend of warm pink and orange.
Coral sits at the intersection of energy and warmth, and it hits the nervous system with a quality of joyful intensity that softer pinks don't carry. It's the colour of flamingos standing in the early morning light and of gorgeous tropical flowers.
When a sunrise looks coral, most people instinctively reach for their phones to capture the moment. What's interesting is that we feel a desire to catch something that's passing by because it feels special.
The Full Palette Together: Why It Moves Us
What makes a sunrise uniquely powerful is not any one colour but the movement between them.
The sky at dawn is never static. It shifts in real time with one colour dissolving into the next making each hue lasting only a few moments. There's a layering of violet and indigo into pink and amber and sometimes into coral and peach. This creates something that no single colour can: A sense of transformation and passing (and it feels fast). I love thinking of it as a symbolic turning of a page, if you happen to be paying attention.
That's perhaps what we really respond to. Not just the colours themselves, but the feeling of being present for something so perfectly beautiful and unrepeatable.
Living With Sunrise Colours
Many of us can't watch the sunrise every morning. Life moves quickly and some days we wake up feeling a sense of urgency already in motion long before we have a chance to step outside and look up.
But what we surround ourselves with has its own subtle influence on how we feel.
The colours of a sunrise (soft pink, warm amber, juicy coral, and glowing peach, deep purples) carry the same emotional qualities in your home as they do in the sky. They activate the same associations: warmth, vitality, beauty, the feeling that something is beginning and worth paying attention to.
Art that holds those colours can become a kind of daily sunrise.
And while catching a real sunrise is one of the best things you can do for your body, mind, and health, that might not be realistic with your schedule. And that's where the colours on your wall come in, always offering a little of what the sky does, every single day.
A moment to pause, take a breathe, and notice something beautiful.
Which, it turns out, is more than enough.
