Your home should reflect you, not Instagram.
Within the walls we choose to surround ourselves, something quieter than aesthetics is at work. Interior designer and colour psychologist Adele Roche reminds us that colour has always been a kind of silent medicine — shaping heart rates, nervous systems, and the quality of our rest long before we had words for why certain rooms felt like refuge and others like unease. The question she returns to, again and again, is not what colour is fashionable or objectively beautiful, but which colours allow a person to feel most fully themselves.
- Colour is not passive — cool greens and blues measurably lower heart rate, while warm reds and oranges raise it, meaning a poorly chosen shade can quietly agitate a household every single day.
- The stakes are real for families with sensory-sensitive children, where a red sitting room can generate enough anxiety that the space becomes entirely unusable.
- Most homeowners make the critical mistake of choosing colours in isolation — a paint sample, a blanket — without considering how each element will live alongside everything else in the room.
- Roche prescribes function-led colour: green for screen-heavy home offices, yellow for active kitchens, and deliberately calming tones for bedrooms, where even a beloved energising colour can rob you of sleep.
- The greatest current danger, she warns, is the Instagram trap — spending thousands recreating someone else's aesthetic, only to find it looks wrong because it reflects someone else's personality, not your own.
Walk into a green room and something physiological happens before you have time to think about it. Your shoulders drop, your breathing slows, your heart rate falls. This is the central argument of interior designer and colour psychologist Adele Roche: colour is not decoration. It is medicine.
Cool colours — greens, blues, purples — recede and lower the heart rate. Warm colours — reds, oranges, yellows — advance and raise it. Walk into a red room already angry and you will leave angrier. Walk into a green room stressed and you will leave steadier. The science is straightforward. What is more complicated is that colour is not universal. Move beyond primary shades and perception fractures — what calms one person energises another. Roche's own happy colour is orange, which makes her feel alive and aligned with her high-energy temperament. She knows others will look at that same orange and see something cheap or wrong. The real question is not what colour is objectively joyful, but which colour makes you feel like yourself.
Most people get this backwards, choosing colours in isolation without considering how they will live alongside everything else. Roche compares it to dressing yourself: your walls are your coat, your floors your trousers, your cushions your earrings. Nothing stands alone. Room function matters too — a home office needs green to rest screen-tired eyes, a kitchen can handle yellow's momentum, but a bedroom is sacred ground. Even if orange is your colour, putting it where you sleep will steal your rest.
Green has surged in popularity since the pandemic, and not by accident. Trapped indoors, people craved the grounded feeling of nature. Green sits in the middle of the colour spectrum, pairs with everything, and provides balance when nothing else does. But trends, Roche cautions, are a trap. She asks clients to stay off Instagram for two weeks before they meet — because when you try to recreate someone else's beautiful room in your own home, and it does not fit your actual personality, it looks wrong. You spend thousands and then you hate it, and that hatred lives with you every day. Your home should be full of colours that make you feel at your best. Everything else is noise.
Walk into a green room and something shifts. Your shoulders drop. Your breathing slows. Your heart rate falls. This is not metaphor—it is physiology, according to interior designer and colour psychologist Adele Roche, who has spent years studying how the hues on our walls reshape the nervous system itself.
Roche's central claim is deceptively simple: colour is not decoration. It is medicine. The shade you choose for your bedroom, your kitchen, your office—these are not aesthetic afterthoughts. They are active forces that either calm you or agitate you, that either support your sleep or sabotage it, that either make you feel at home or make you feel like a guest in your own life. The science is straightforward. Cool colours—greens, blues, purples—recede into the background and lower your heart rate. Warm colours—reds, oranges, yellows—advance toward you and raise it. Walk into a red room angry and you will leave angrier. Walk into a green room stressed and you will leave steadier.
But here is where it gets complicated: colour is not universal. Two people looking at the same wall will not see the same thing. Primary colours are the exception—red is red, blue is blue. But move into secondary territory and perception fractures. What you see as orange, someone else sees as red or yellow. What calms one person energises another. Roche's own happy colour is orange. When she sees it, she feels alive, electric, aligned with her own high-energy temperament. But she knows others will look at that same orange and see cheapness, tackiness, something childlike and wrong. The question is not what colour is objectively happy. The question is: what colour makes you feel like yourself?
This matters because most people get it backwards. They choose colours in isolation—a blanket they love at the shop, a paint sample that looked good in the can—without thinking about how it will live with everything else. Roche compares it to dressing yourself. Your walls are your coat. They touch everything. Your floors are your trousers. Your cushions are your earrings. Nothing stands alone. A bright pink bedroom might be exactly right for your daughter, but only if she chose it, only if it reflects who she is rather than who you think she should be. Couples fight about this. One partner claims not to care until the paint dries and suddenly they hate it. Families with children who have sensory sensitivities face real stakes—a red sitting room can raise a child's anxiety so high they will not use the space at all.
Room function matters too. A home office where you stare at screens all day needs green—it provides balance, it rests the eyes. A kitchen, where your body is constantly moving and your mind is juggling twenty tasks at once, can handle yellow's energy. But a bedroom is sacred ground. Even if orange is your colour, even if it makes you feel alive, do not put it in the room where you sleep. It will keep you restless. It will steal your rest. Roche suggests colour blocking—yellow in the kitchen where you need momentum, something softer in the dining room where you want to linger. Let the function of the space guide you.
Green, she notes, has become fashionable in the last two years. But it did not become fashionable by accident. During the pandemic, when people were trapped inside, they craved the feeling of being outside, of being grounded in nature. Green is the colour of balance—it sits in the middle of the spectrum between cool and warm. It pairs with everything. It is the all-purpose shade, the one that works when nothing else does.
But trends are a trap. Roche works with paint companies and understands the machinery of fashion. On a personal level, though, she strips it all away. She asks clients to stay off Instagram for two weeks before they meet, to stop absorbing what everyone else is doing. Because here is what happens: you see something beautiful on social media, you try to recreate it in your home, and because it does not fit your actual personality, it looks wrong. You spend six or seven thousand euros painting your house and then you hate it. And that hatred lives with you every day. Your home should reflect you. It should be full of colours you are comfortable in, colours that make you feel at your best. Everything else is just noise.

If you go into a green room, where the colour is softer, it will reduce your heart rate and help you calm down— Adele Roche, interior designer and colour psychologist
You need to make sure your home reflects you and is full of colours you're comfortable in— Adele Roche
A Conversa do Hearth Outra perspectiva sobre a história
So when you say green reduces your heart rate, is that something you can feel immediately, or does it take time?
You feel it. Not always consciously, but your body knows. If you're agitated and you step into a green space, there's a settling that happens. It's not dramatic—it's subtle, like the difference between holding your breath and breathing normally.
And the warm colours do the opposite?
They advance. They demand attention. Red especially—it's not bad, it's just active. Your nervous system responds. If you're already wound up, red will wind you tighter. But if you're sluggish, if you need to move, red can help.
So it's not that red is a bad colour.
Not at all. Red in a kitchen where you're cooking and moving—that's fine. Red in a bedroom where you need to sleep—that's working against you. It's about matching the colour to what the room is supposed to do.
What about people who just love a colour, regardless of what it does to them?
Then you have to be honest about the cost. If orange is your colour and you paint your bedroom orange, you're choosing energy over sleep. That's a real trade-off. Some people are willing to make it. Most aren't, once they understand what they're choosing.
Is there a colour that works everywhere?
Green. It's the middle ground. Cool enough to calm, warm enough to feel alive. It goes with everything else in your home. It's become trendy, but the trend started because people needed it—they needed to feel like they were touching nature while they were stuck inside.
