Boobs!! Now that I have your attention, let's talk about colors :P

Let's sit down and enjoy this colorful butterfly for a second. isn't she beautiful, so calm, and minding her own business.

But have you ever wondered why does she look blue? Why anything has colors at all? What exactly is color? What is light? to answer that, let's go small, How small? atomic small.

A visible light is an electromagnetic wave, (Technically its particle and wave at the same time, but since we are talking about colors, we are considering only the wave aspect of the light.)

All waves have a property called "Wavelength." Wavelength is the measure of the length of one complete cycle.

A particular range of the wavelengths is called spectrum. Let's have a look at the different spectrums of the electromagnetic waves.

In the picture above the highest wavelength, electromegnetic waves are the radio waves, and the gamma rays have the smallest wavelength.

Between this huge spectrum of the electromagnetic waves, the visible spectrum is the only range we can see through our naked eyes.

And when we expand the visible spectrum, we can see the range of the colors we are able to see through our eyes.

When combined all the light in the spectrum above, we get white light.
a white light is the combination of all the color range above. while in school you might have conducted an experiment involving a prism.

A Prizm refracts different spectrums of light, differently depending on the refracting index. so they end up in the different places as per their refractive index.

Reflection and Refraction

When the light bumps into a surface and bounces off and changes the direction, the process is called Reflection. And when the light travels through a varying density the light gets deflected and continues to travel into the new medium. the process is called Refraction.

When a white-light(A combination of all the colors) hits an object then depending upon the molecular structure, most light gets absorbed by the object, and certain wavelengths (Color) are bounced back. This is why the object has a certain color.

Transparent objects like water let the light through and do not absorb any light, hence we can see through them.
in short Different colors = Different wavelengths.

There's one very common color which is not available in the rainbow. can you name it? write down in the comments below.

And since you were expecting some titties, Here is the picture of a tit.

Yes, i know its a bird, but its called "Titties" you perv. Did you really think I would post a picture of the breasts? No sir. :P
