Visible light colors are a small part of the overall collection of waves on the electromagnetic spectrum. You can remember the order of teh light colors with respect to their corresponding wavelengths, from lowest to highest, by using the mnemonic "ROY G. BIV". The letters correspond to the colors, which are red, orange, yellow, green, blue, indigo, and violet.
When we see a particular color, such as spinach green or papaya yellow, what is happening is sunlight, which is composed of all the colors, is radiating upon the spinach and papaya. All the colors are absorbed except that specific colr, which is reflected back from the object. That is why spinach appears green, and papaya appears as yellow, because those specific colors are reflected, while all the other colors are absorbed. It should also be noted that all the colors combine to give what is known as "white light"; this may be demonstrated by taking a prism and allowing sunlight to shine through it. The result is a rainbow, showing the respective colors white light is made of.
