How many colours are there?

How many colours are there?




How many colours can you see in this image? (Answer in the last)


Well the main question is, How many colours are there in total?

Some say there are 3 colours (red, green and blue). Some say it would be in 100s to 1000s. But, Scientists have determined that in the lab we can see about 1,000 levels of dark-light and about 100 levels each of red-green and yellow-blue. So that's about 10 million colors right there. 

Still, the exact number remains unknown. But it is believed that the exact number would at least be greater than 10 million.


So, How many colours can a human eye see?

The human eye can see around 7-8 millions of colors. But believe it or not, some colors exist in our world that the human eye can’t see. So, a healthy human eye can not see 2-3 million colours that actually exists in our world.

Humans don’t typically develop full color vision until they are about half a year or so old. The retina in the back of your eye has millions of tiny parts called cones. There are three kinds of cones typically found in the human eye: red, blue, and green. It’s these three kinds of cones that work together and allow you to see millions of colors.

The answer of the 1st question is 39. There are total 39 colours in the image. If you can see all the 39 colours, you have tetrachromatic vision. Much like bees, you possess four different kinds of cone cells in your eyes and see the majority of colours in the visible light spectrum. Only 25% of people can see all the colours in the image.


I hope you liked the post. See you all in the next post...

What is a Universal Donor & Recipient?

  Universal Donor and Recipient There are 4 types of blood: Type A                                • Type B Type AB                              • Type O Universal Donor -A universal blood donor is a blood type that can be donated to any type of blood. The rarest blood type, O negative is considered to be a universal donor throughout the world. It can be donated to any person as it has no antigens. No antigens means that antibodies will not attack. Thus, it is compatible with all other blood types.  But now, some experts believe that this isn't true. They believe that O negative might have antibodies that can cause a serious reaction during blood transfusions. What is the rhesus (Rh) factor? The rhesus factor refers to the red blood cell antigen in the body's blood. If you have the antigen, then you are Rh+. If you don't, ...

Knuckle Cracking

 Knuckle Cracking Before knowing what happens when we do knuckle cracking, let's see why people do this? Most of the people usually crack their knuckles to get relief from stress or nervousness . Some think that it's cool while others just do it for fun.   But do you know what actually happens when you do this? There can be different reasons for the cracking sound produced. They are: 1. Escaping Gases:   The synovial fluid present in our joints acts as lubricants. This fluids contains many gases such as oxygen, nitrogen and carbon dioxide . When we crack or pop a joint, we stretch the joint capsule. This stretching causes the gas to release rapidly. During this, it releases carbon dioxide bubbles. The cracking sound may be produced due to the movement of synovial fluid back into the gas cavity. It is due to the movement of gases (from synovial fluids) that we have to wait for around 15 mins to crack the same knuckle again. 2. Movement of joints, tendons and ligaments: ...
