You’ve seen them since kindergarten. Those bright, glossy posters pinned to classroom walls, usually with Greenland looking like a giant icy monster and Africa looking surprisingly small. We call it a colored map of the world, but honestly? It’s a compromise. A big, colorful, beautiful lie.
Maps are basically flat versions of a round reality. You can't peel an orange and lay the skin flat without it tearing or stretching. So, cartographers—the folks who make maps—have to choose what to break. Do they break the shapes? The sizes? The directions? Most of the maps you buy for your home office or see in a textbook choose to preserve direction, which makes the colors look great but messes with the scale of our planet in ways that have actually shaped how we view different cultures.
The Mercator Problem and Why Color Matters
Gerardus Mercator created his famous projection in 1569. It was for sailors. If you’re on a ship in the middle of the Atlantic, you need straight lines to navigate. Mercator gave us that. But to keep those lines straight, he had to stretch the areas near the poles.
This is where the colored map of the world gets tricky.
On a standard Mercator map, Greenland and Africa look roughly the same size. In reality? Africa is fourteen times larger. You could fit the USA, China, India, and most of Europe inside Africa, and you’d still have room for change. When we splash bright colors across these shapes, it reinforces the "size" in our brains. A bright red Greenland feels massive and dominant. A tiny yellow India feels insignificant. This isn't just a geography nerd's complaint; it’s a cognitive bias. We associate size with importance.
The Gall-Peters Alternative
If you want accuracy in size, you look at the Gall-Peters projection. It looks "weird" to most people because the continents look stretched vertically, like they’ve been pulled like taffy. But the landmasses are sized correctly relative to one another.
When you see a Gall-Peters colored map of the world, the visual hierarchy changes instantly. The Global South—South America, Africa, Southeast Asia—dominates the visual field. It’s a humbling perspective. Many NGOs and social justice organizations prefer this version because it stops the visual "shrinking" of developing nations.
Aesthetics vs. Information: Choosing Your Palette
Why are maps colored the way they are anyway? There’s no international law saying France has to be purple or Brazil has to be green.
Historically, map coloring was a high-art form. In the 17th century, hand-colored maps used expensive pigments like lapis lazuli for blues or cochineal for reds. Today, most maps fall into two buckets: political and physical.
- Political Maps: These use colors to distinguish borders. The "Four Color Theorem" is a mathematical rule here. It proves that you only need four different colors to shade any map so that no two adjacent countries share the same color. It’s a fun bit of math that keeps maps from looking like a chaotic mess.
- Physical Maps: These use color to show elevation or climate. Green for lowlands, brown for mountains, white for ice. This is what we call "hypsometric tints."
But here is a fun fact: the blue used for oceans on a colored map of the world hasn't always been the standard. Early maps often left the sea white or filled it with illustrations of sea monsters and wind gods. The deep blue we expect now is a relatively modern printing convention.
The Psychology of the "Bright" Map
Colors aren't neutral.
Think about it. If you see a map where the Middle East is shaded in a harsh, dusty brown and Europe is a lush, vibrant green, your brain makes a judgment. You think "dry and desolate" vs. "fertile and wealthy."
Cartographers like Cynthia Brewer (who created ColorBrewer, a legendary tool for map design) have spent years studying how color affects data perception. If you use a high-contrast palette, like neon pink against dark blue, it highlights borders and suggests conflict or separation. If you use a "sequential" palette—different shades of the same blue—it suggests unity or a gradient of data, like population density.

I once saw a colored map of the world designed for kids that used different patterns instead of solid colors. It was a disaster. The human eye loves a clean color fill. It helps us categorize information instantly. We "chunk" the world into regions based on those shades.
Why You Should Care About the Dymaxion Map
If you’re tired of the Mercator vs. Peters debate, look up Buckminster Fuller’s Dymaxion map. It’s a 1943 invention that unfolds the Earth into a 20-sided shape.
Fuller’s goal was to show the world as one continuous island in one continuous ocean. There is no "up" or "down." No North or South. It’s arguably the most "honest" colored map of the world because it doesn't distort the size of the continents much at all, and it doesn't have a cultural "center."
It’s just harder to hang on a wall because it looks like a jagged explosion of triangles. But for a true sense of how humans are connected, it’s unbeatable.

Digital Maps and the Death of Static Color
We’re moving away from paper. Most of us interact with a colored map of the world through Google Maps or Apple Maps.
These maps are "dynamic." They change color based on the time of day (dark mode) or the traffic levels. In 2020, Google Maps rolled out a massive color update using computer vision to identify natural features from satellite imagery. Suddenly, we could see the difference between a desert, a forest, and a shrubland just by the specific hex code of green or beige used.
This is the future of cartography. It’s not just about "where is the border?" but "what is the ground actually like?"
Finding the Right Map for Your Wall
If you're looking to buy a map for your home, don't just grab the first one you see at a big-box store. Think about what you want it to say.
- For a classic look: Go with a "National Geographic" style. They use muted tones and very readable fonts. It’s the gold standard for a reason.
- For a modern vibe: Look for "minimalist" maps that use only two colors. They strip away the clutter and focus on the silhouette of the continents.
- For accuracy: Find a "Winkel Tripel" projection. It’s the one National Geographic adopted in 1998 because it strikes the best balance between size and shape distortion.
Actionable Steps for Map Enthusiasts
- Check the Projection: Before buying a colored map of the world, look at the bottom corner. If it says "Mercator," know that the sizes are wrong. If it says "Winkel Tripel" or "Robinson," you’re getting a much more realistic view of the planet.
- Audit Your Biases: Look at Africa and South America on your current map. If they look small compared to Europe or North America, your map is reinforcing an old-school, Eurocentric view.
- Explore Interactive Layers: Use tools like "The True Size Of" website. It lets you drag countries around a digital map to see how their size changes as they move away from the equator. It’s the fastest way to un-learn the distortions of a flat map.
- Support Small Cartographers: Sites like Etsy are full of independent artists making maps that use data visualization (like "The World as a Subway Map" or "The World by Population Density"). These offer way more insight than a generic office supply store version.
Stop looking at the world as a static, colored-in coloring book. Every map is a tool designed for a specific purpose. If your purpose is to understand the actual scale of the human experience, you might need more than one version of the world on your wall.
The map is not the territory. It's just a snapshot of how we choose to see it. Next time you see a colored map of the world, look at the poles, look at the equator, and remember that someone, somewhere, had to choose which parts of the truth to stretch and which to keep.
