Colours – part 04. Mix the colours!

                Welcome to the fourth discussion on the ‘Colours!‘. The topic is getting so exciting and I am very much enjoying it. I am sure you are enjoying the series too, aren’t you?

                Before going ahead, let’s take a quick recap of the first three posts we talked earlier. In the first post, we talked about our relative sensory system, due to which we can see. In the second post we discussed how we ‘see’. How the light emitted from the source gets converted into a brain signal. And further in the third post we met Mr. Light, talked how the ‘Electro-Magnetic Radiations’ of different wavelengths are ‘seen’ as different colours to us. Now today, we will be taking the topic ahead.

                So we now know that, our eyes has three types of ‘Cone’ cells that works as receptors of three wavelength rays. These three wavelengths are seen as ‘Red‘, ‘Green‘, and ‘Blueish‘ in colour. In our eye retina,  the count of such cones is about 2,50,000. Continue reading

Colours – Part 03 (more light on colours)

Since last two posts, we have established a good tempo and talking about Colours! Right? Yesterday, I was compiling all the notes for this post and was sorting topics. And while doing that, I was sort of thinking to ask my doubts to some one who can answer me well. While thinking about that I started dreaming of a meeting with such a one. I immediately called him and asked for his appointment and to my surprise he agreed. And you know what? Today, We have that very spacial guest with us.
‘Mr. Light’ himself. Yes The Great Mr. LIGHT HIMSELF! Ta Da!
Me: Hello Sir!
Mr. L: Hi Mahesh, how are you?
Me: I’m Great! Its my pleasure to see you. And how do you do, sir!
Mr. L: Pretty straightforward. But Mahesh, I am afraid that I have very short time for discussion now. I have to go to my friends birthday. Her name is twinkle. In next 15 seconds I have to reach there. So ask it quickly.
Me: OK, OK. Sir. I will ask you as fast as possible! I was discussing with my friends about how do we ‘see’. Can you describe us, how do we humans see colours? We would love if, you will put some light on that.
Mr. L: OK Time’s up. I need to go now. I will talk with you later! Till then why don’t you google about that your self? Hmm?
And suddenly a big flash of light crossed over my head and then… Continue reading

Talk on Colours – Part02

Hello everyone,

We were talking about a very very wonderful subject – the colours – since the last post. Now we will continue our discussion further.

So, the question arrived earlier was – How do we actually see?
 For us to see anything, it needs at-least these four things.
  1. A light source
  2. An object to look at
  3. The Eye and …
  4. (We will talk about the 4th in just a minute)
The first thing needed is a light source, from which some amount of light is emitted.

Secondly, an object (of course!) to look at has to be there. Continue reading

Colours, wishlisted topic

Quote

Colours! What a great and beautiful topic to discuss about. I am feeling really joyful to announce that for next few days we will be talking about such a wonderful topic.

We all know the importance of colours. Colours play a very significant role in our day to day life. Colour is the basic and most primary form of our knowledge of the world that surrounds us. Because of the colours we percept or interpret our environment. Colours are the very alphabets of one of our most prominent senses, the vision. Sight is the most vital sensory system among the five. And with colours we ‘see’, we communicate, we interact, we learn and we do all our activities.

The topic ‘Colour‘ has got both, the scientific side as well as the creative. Of course we are more interested in the creative side, where Continue reading
