A diagram showing the wavelength sizes of the colors of the visible spectrum. (Notice: When Issac Newton was first defining the concept of the colors of the rainbow (which contains all of the colors in the visible spectrum), he defined cyan as being the «blue» and the actual blue being the «indigo»)

People think of objects as having color. The actual explanation for color is because the molecules that make up the object absorb certain light waves of color, leaving the other light waves of color to bounce off. The human eye sees the wavelengths of all of the light that was not absorbed, and the combination of those colors gives the brain with the impression of a color. A white object would absorb almost no light, while a black one would absorb almost all light hitting it. Red objects reflect only red light and absorb all the other colors.
