Asasalamualaikum....actually I want to share about the colours...Well,the retinas in our eyes have three types of colours receptors..From my reading,i just know that we can only detect three of the visible colours which red,blue and green.These visible colours also known as additive primaries.It is these three colours that are mixed in our brain to create all of the other colours we see such as orange,grey,purple,yellow and others.Basically,the wavelength and frequency of light also give effect to the colours we see.The seven colours of spectrum have varying wavelength and frequncies.
That's all from me
