The Science Of Colour and Your Eyes - How Many Colours Do You See

I came across this interesting article via a friend, and wow was I surprised!

I guess I've always known that people see colours differently, and not just 'colour blind' people. But when I saw this, and counted the number of colours I could see, I was shocked!

Your eye is made up of a lot of things, but you will have either 2, 3, or 4 colour cones.

Take a look at the below image and count how many different colours you can see:

How many did you get?

Under 20 - you have 2 cones in your eyes (dichromats)

Between 20 & 33 - you have 3 cones in your eyes (trichromat)

Over 33 - you have 4 cones in your eyes, along with only 25% of the population. (tetrachromat)

Check out the full article with more information, for instance tetrachromats hate the colour yellow, and dichromats probably wear a lot of black, brown and beige.

I saw 36 colours. How many did you get? Let me know in the comments below!
And no, I'm not going to ask you what colour the dress is :/

Too easy? Check the 3 circles below.

The majority of people will see 3 circles filled with smaller coloured dots of the same colour. If you see anything different, such as something in the little coloured dots, you're a super human!

What do you see?

Apparently all these tests are inaccurate (but I still found them fun)
Here's a more complex one
