it simply means that the rainbow (rainbow is a visible spectrum) that we see on the sky (the rainbow with r, o, y, g, b, i and v) actually come from white light.... (white light is like divided to spread to form a spectrum with the use of water droplets that act as a prism)
we see things because of light that is reflected from objects right? (yeah)
so if you have a red paper, the light reflected from the paper is red light (the red part of the visible spectrum)... so if you have a white paper, you see all colors of the visible spectrum... but if the paper is black, all other colors (light) is absorbed....
(i simply love optics)

I think that is the simplest form already. Now, for a more complicated explanation:
What it means is that color depends not only on the thing, but also on the light you use to see the thing. White light is actually a micture of all possible colors of light. Have you ever hear the question, "Is a brick still red in the dark?" To your eyes, the brick, and everything else, is black in the dark. If the only light in the room is a green light, the brick will look black too, because red objects do not reflect green light. So the color of things depends not only on the nature of those things, but also on the nature of the light shining on them. Now, when I say reflect light, I don't mean like a mirror. Mirrors are polished smooth so that each light ray is reflected at the same angle to make an image. A rough surface reflects each light ray in a slightly different direction, so you don't see any image in the reflection, just a lot of mixed up light.

White is the color that is made by the reflection of all other colors on the spectrum equally.

What we see as colors are actually electromagnetic waves at certain wavelengths. However, there is no wavelength corresponding to white. White is actually made of a wave containing the entire spectrum of visible light wavelengths. So when you see something as white, you are in essence seeing all colors at once.

light is a mixture of 7 colors- red, orange, yellow, green, blue, indigo and violet. An object absorbs some colors and reflects a particular color. That will be the colour of the object.

When all visible light is reflected you see white. When all light is absorbed you see black. For other colors, such as red, all the colors except red are absorbed and red is reflected.
