Observing this wasn’t planned exactly before, though boredom got the best out of me. Studying for exams were a bit tedious thing… hence this is what I did. Armed with a foldscope, all I could see was my target which was the computer screen, which had all ebooks in it which I was reading at that time.

I took the foldscope and pressed the lens hard against the screen. And indeed it looked nice. Many people do not know this but all colours we see on screen are obtained only from three colours. Namely – red, blue and green.

The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors.  The principle of RGB lies in a phenomenon – trichromatism. Trichromacy or trichromatism is the possession of three independent channels for conveying color information, derived from three different cone cells in the eye.
