You ever walk into a room and just feel... off? Like the walls are screaming at you, or maybe they're so dull they’re sucking the soul right out of your chest. It’s not just you being picky. There is a legitimate, scientifically backed reason why the colours of my world—and yours—dictate how we sleep, how we work, and even how we digest our dinner.
Color isn't just decoration. It’s physics.
We’re talking about specific wavelengths of light hitting your retina and triggering the endocrine system. When you see red, your heart rate actually ticks up. That’s not a metaphor; it’s a physiological fact cited by researchers like Andrew Elliot at the University of Rochester. His work on "color psychology" shows that even a brief glimpse of red before a test can tank your performance because it's wired into our lizard brains as a danger signal. On the flip side, we’ve got people painting their bedroom walls "Millennial Pink" or "Sage Green" because they’re desperate for a hit of dopamine after a ten-hour shift.
The psychology behind the colours of my world
People get it wrong all the time. They think blue is just "sad" or "calm." Honestly? It’s more complicated.
If you spend all day staring at a bright, high-energy cyan, you might be productive, but you're also frying your circadian rhythm. This is why "blue light" is the villain of the 21st century. Your brain thinks it’s noon when it’s actually 11 PM. If the colours of my world are dominated by these short-wavelength lights late at night, melatonin production hits a brick wall. You end up staring at the ceiling for hours.

Why yellow is actually kind of exhausting
Everyone says yellow is the color of happiness. It’s sunshine and lemons, right? Well, sort of. While it can be cheery in small doses, chromotherapy experts—and even interior designers who’ve been in the game for thirty years—will tell you that a completely yellow room is a nightmare. It’s overstimulating. Babies have been shown to cry more in yellow rooms, and adults get irritable. It’s too much information for the eye to process at once.
The trick is balance. You don't want a "theme." You want a lived-in spectrum.
When I look at the colours of my world, I'm looking for "visual ergonomics." This means using colors that reflect your actual needs. If you're a high-strung person, your house shouldn't look like a Ferrari showroom. You need low-saturation tones. Think oatmeal, dusty rose, or slate. These aren't "boring" colors; they’re a tactical choice for sanity.
The cultural baggage of the palette
We can’t talk about the colours of my world without acknowledging that color meaning isn't universal. It’s a messy, beautiful mix of biology and history.

In many Western cultures, white is for weddings—purity, new beginnings, all that. But hop over to parts of China or India, and white is the color of mourning. It’s what you wear to a funeral. If you’re a global brand—or just someone trying to be culturally literate—you can’t just assume "green means go." In some South American cultures, green can be associated with death.
- Red: Luck in China, danger in the US, mourning in South Africa.
- Purple: Historically the color of royalty because the dye (Tyrian purple) was so expensive it was literally worth its weight in silver.
- Orange: Spiritual in Buddhism, but in the Netherlands, it’s a fierce national identity thing.
It's wild how much we let these invisible rules dictate our lives. You’ve probably bought a product because the packaging was a specific shade of "trustworthy" navy blue without even realizing it. Brands like Ford and Visa use blue for a reason. They want you to feel like they aren't going to lose your money or explode on the highway.
How light changes everything
A color doesn't exist in a vacuum. It’s a shapeshifter.
The colours of my world at 6 AM are totally different from what they look like at 4 PM. This is the concept of "Metamerism." It’s why that paint swatch looked perfect at Home Depot but looks like baby vomit in your living room. The light source—whether it’s North-facing natural light, warm LED, or that horrific flickering fluorescent office light—changes the molecular appearance of the pigment.

If you want to master your environment, you have to test colors in the "worst" light of the day. Usually, that’s around 3 PM when the shadows get long and weird. If you still like the color then, it’s a winner.
Practical steps to curate your environment
Stop following trends. Just stop. "Peach Fuzz" or "Viva Magenta" might be the Pantone Color of the Year, but if those colors make you want to scream, don't put them in your house.
To actually fix the colours of my world, you need to do a sensory audit. Look at your most-used spaces. Are they helping your goals?
- For Sleep: Move toward "warm" darkness. Dim lights that are heavy on the red/orange end of the spectrum. This mimics a sunset and tells your brain to start winding down.
- For Focus: Use "cool" whites and blues during the day. This mimics the high-noon sun and keeps cortisol levels high enough to actually get work done.
- For Eating: Avoid blue plates. There is almost no blue food in nature (blueberries are actually purple/black), so our brains often interpret blue as "moldy" or "poison." It’s an appetite suppressant. If you’re trying to enjoy a meal, go for warm tones like terracotta or wood grains.
Instead of repainting every wall, start with the small stuff. Swap your lightbulbs for smart bulbs that change temperature based on the time of day. Change your desktop wallpaper to something that actually relaxes your eyes—usually something with a deep depth of field and natural greens. These micro-adjustments to the colours of my world add up. They reduce the "cognitive load" your brain has to deal with every second you’re awake.
The goal isn't to live in a rainbow. It's to live in a space that doesn't fight against your biology. Start by looking at your bedroom lamp tonight; if it's a harsh, "daylight" white, swap it for a warm amber bulb. Notice how your shoulders drop two inches within ten minutes. That's the power of color working for you, not against you.
