Here's what 10 famous US landmarks look like if you're colorblind

Shutterstock/karamysh/CoblisThe flowers in Skagit Valley Tulip Fields look different to people with colour blindness.

About 8% of men and 0.5% of women with Northern European ancestry have red-green colour blindness, according to the National Eye Institute. Depending on the type of colour blindness, they might see colours less vibrantly or not be able to see certain colours at all.

While being colorblind doesn’t tend to significantly hinder one’s daily life, it can make tasks such as reading colour-coded charts, buying ripe produce, picking out matching clothes, and reading maps difficult. Travellers with colour blindness might also find that they see famous landmarks differently.

We put photos of 10 US landmarks through an online colour blindness simulator called Coblis to see what they would look like with different kinds of red-green colour blindness.

Here are 30 photos that show what beautiful US destinations look like if you’re colorblind.


The Grand Canyon contains red and orange layers of rock with normal vision.

It’s one of the Seven Wonders of the World.


With protanomaly, it looks more brown.

Protanomaly is a type of colour blindness where red cone photopigments are abnormal and colours don’t appear as vibrant.


Protanopia eliminates most of the colour differences.

Protanopia means that there are no working red cone cells at all – red often looks black and orange, yellow, and green all look yellow.


People come from all over the world to see the Skagit Valley Tulip Fields in Washington.

Last year, the annual tulip festival attracted people from all 50 states and 93 countries.


If you have protanomaly, the bright pink tulips appear more of a muted dusty colour.

With protanopia, the tulips blend in with the leaves.

It is hard to tell that these are tulips.


Yellowstone National Park’s Grand Prismatic Spring gets its colours from bacteria living around the spring.

The water comes from a crack in the ground running 121 feet deep.


Protanomaly mutes the vibrant rings of colour around the spring.

The different colours are still visible.


With protanopia, there’s no distinction between any of the colours.

All of the rings look yellow.


The Wave in Coyote Buttes North, Arizona, became famous as a Microsoft desktop image in 2009.

Because of its fragility, the Bureau of Land Management only allows 20 people to visit per day as determined by a lottery.


The Wave looks more brown to someone with protanomaly.

It’s less orange.


With protanopia, the Wave looks more yellow but the lines are still visible.

People with colorblindness can still see the effect.
