Hi Allison, This is in regard to your question about why dark colors absorb more light. The answer is something like this.. All objects absorb radiation (energy)in nature. Light is also a form of radiation (energy). When white pure light falls on an object the object absorbs a part of it.... and reflects a part of it. When all the light incident on the object is reflected then we get to see white color. When all the light incident is absorbed we see the object to be colorless (or in other words black). So scientifically black is not a color. It is the absence of all colors. Now "How do we get different colors then?" Let us take the example of yellow color. When white light falls on a yellow object the object will absorb all colors (that is violet, indigo, blue, green,orange and red) but not yellow. So yellow is reflected from its surface. Now as radiation is energy the more the amount of light absorbed the more it will heat the body. White absorbs the least energy and will be heated the least. Pale colors have more of white in them and hence they too reflect most of the light falling on them. The opposite happens for dark colors. They absorb the most energy and hence get heated fast. Hope you have understood what I am trying to say. If not E-Mail me at "firstname.lastname@example.org" and tell me what exactly you have not understood. I shall try my best to explain. Nauzad Tantra.
