Why
is the sky blue ? |
|
| This
is a summary of a previous article. (Why-is-the-sky-blue). My conclusion is a simple straight line equation : The sky is blue because the sun is gold. It is based on the common sense observation that the color of a shadow is the complimentary opposite of the color of the emitted light. The following easy to understand web site explains this phenomenon: |

| www.newtrier.k12.il.us...coloshad... There is also a simple graph to show which colors are opposite to which, but this should be common knowledge in the age of multimedia. |
 |
| In the following photographs, taken from arbitrary google searches such as 'red light bulb', one can quite easily see how this happens. (Websafe hexadecimal color codes are after the #) | |

 websafe shadow #336666 websafe light #CC3300 |
| The
background color for each frame has been
extracted by macromedia dreamweaver from the shadowed part of the photo
using the extractor tool, and translated into websafe color. So has
the light for each picture. |

 websafe shadow #003366 websafe light #FFFFCC |
 This website explains all of this quite neatly. |
|
If you take the time to understand how hexadecimal color is calculated
(simpler than it looks) you will see that the shadow is the opposite
to the color. Nobody can dispute this. Not even the Goth chick. |

Try the experiment yourself using various light bulbs. Photograph the
effects and use a color extractor in any graphics program to get the
approximate color values of the light and its shadow. Remember that
you have to get some shadow into the photo, so a close up of the light
will not help much. Back away a bit. Now! Where is the big blue shadow one would then expect to find in the wake of the Sun's yellow-orange (gold) light? Hmmm? Perhaps its hiding out somewhere with all those missing weapons of mass destruction? It follows there must be a big big blue shadow somewhere? Because we have a big big gold light in the sky! The sun is a type G star, an 'Orange dwarf'. (Just in case your city has so much pollution or bad weather so that you cannot see the sun much, and assume it is 'white' in color.) And it follows that the color of a shadow would fall most brightly on a colorless substance. Like water. Or sky. Or just the shadow on a plain white wall, or swimming pool. |
