How we visualize Colors?

From the Day we born we had some powers in which one of most beautiful power is Ability to See and Visualize Things and Don't even Focus How can it possible that these scenes that In-front of our eyes are so colorful? One of Interesting Facts that I observe only 20% People Think About that How can we see Colors; Of-course with Eyes But A Scientific Story Behind it.

Eye Power: A Human Eye Lens is about 576 mega pixels that gives much more clear vision than A Stranded Digital Single Lens Reflex Camera that are about 16 Mega Pixels usually. Pupil of our Eyes allows light to enter for sake of seeing and Iris Controls the Amount of Light.

Luminous Light: The Light is Source of Energy or also knows as Electromagnetic Radiation that comes from sun naturally or change of motion in particles. Moreover Light had Wave-Particle Duality According to its Nature it does not need any specific medium to pass But it can pass to any kind of medium.

Electromagnetic Radiation Spectrum Chart: The Electromagnetic Radiation Spectrum had many Seven Types of Radiations in which Microwave Waves,Radio Waves,Inferred Waves,Ultra-Violet Waves, X-Rays and Gamma Rays,Visible light.

All these Types of Electromagnetic Radiation are widely used now a days for Research for Betterment of Science Future.The Visible Light Befalls between Inferred Waves and Ultra-Violet Waves. 

Visible Light:

From the Research it defines that we can see Wavelengths of light within the limit Naturally. From Spectrum Visible Light Chart is about 380 to 740 nano-metres that Human eye can see. Did you notice  There is Seven Colors in that Chart that usually had Rainbow. Here the Interesting Fact That Visible light had seven colors and Electromagnetic Spectrum had seven types. 

Objects in Light:

When we see objects in Light. The Visible Wavelength of Light Colors in some of these are absorbed or other are reflected from Object towards our eyes.

Here's a Question which colors of Light Absorbed in Object or which colors of Light Reflected from Object? Objects had Property to Absorb or Reflect Wavelengths of Spectrum of Light. The Color that Already Exist in Object are Reflected In-front to our eyes or The colors that are not present in Object that absorbs in it.

Full Absorption and Reflection: 

Two Colors that fully Absorbs and Reflects wavelengths of Visible Light.The Object that had white Color Reflects all Wavelengths of Visible Light that's why it looks white Because white color had all Wavelength of visible light itself and The Object that had Black Light Absorbs all Wavelengths of Visible Light or reflects none it is also called Black Body Radiation because black object Absorbs all electromagnetic wavelengths or nothing can Reflects from it that's reason it shown as Black and emits thermal radiation  continuous due to its property of Absorption or According to Temperature.
