How to Make a Spinning Color Top

TODO Link from History of Color section about Maxwell to here when I have control of the page .

Back in the mid 18th century, Munsch and Ignaz Schiffermüller devised an ingenious way of experimenting with additive color mixing. They attached a disk to a top. The disk was colored with different portions of the primary light colors, red, green and blue. As they spun the disk very fast, the colors blended together to form a new color or hue.

A century later, James Clerk Maxwell and Ogden Rood developed a number of color theories using this spinning top.

How the Spinning Color Top Works

The disk is divided into three pie shaped areas. The areas can be any size and are the primary colors, red, green and blue. Spinning the disk creates an illusion of one single, pure hue of a color. The light reflected from the colors is visually mixed together causing the illusion. We can find out what mixture of primary colors is needed to make the hue we see by measuring the proportion of primary colors on the disk.

How to Make a Spinning Colored Top

[TODLK - Top Design picture.]

You can easily make your own spinning top with these simple items. You will need:

• Pencil with a point
  
  
• Tape or glue
  
  
• Piece of paper, heavier is better

Open one of these pdf files and print it. Cut out the colored circle.

Take your pencil and poke it through the center of the circle. It might help to cut the center open with an Exacto type knife.

Tape or glue the pencil in place, leaving enough room below the disk for your hands to spin it.

Spin!

Cells are sized by the largest cell in a column. To make the cells larger, put nbsp in them. But make every other one a regular space (use a space in the text) becuase it takes less code and allows a carriage return to be inserted if someone's screen is small. Otherwise, they will have to scroll back and forth.

If no table border (tb1, ex.) is defined, the default is tb0, or no border around the cells.

To have a different background color, go to cssoptions in IncColors and put an X in colorsbg to enable this feature. Define the class for the bg color.

To have no borders:

• Do not define a border (ex., tb1). The default is no border.
• Define style="background:#xxxxxx" where xxxxxx = the color code of the bg color.

HIDDEN UNIQUE TEXT MARKER:

The first essential to the application of the Munsell Color System is a clear understanding of the three dimensions of color. Once the simple logic of these dimensions is grasped, the practical advantages of the Munsell System will be apparent.

To Redirect a File:

Open an existing php file using NoteTab. Delete everything and replace it with the following code. Save with NoteTab, making sure it is still a php file.

function redirect($to)
{
$pc = $_SERVER['SERVER_PORT'] == '443' ? 'https' : 'http';
// $host = strlen($_SERVER['HTTP_HOST'])?$_SERVER['HTTP_HOST']:$_SERVER['SERVER_NAME'];
if (headers_sent()) return false;
else
{
// header("HTTP/1.1 302 Found"); HIGHLY SUGGESSTED YOU DONT USE THIS !!!!!!!!
// header("HTTP/1.1 303 See Other");
header("HTTP/1.1 301 Moved Permanently");
header("Location: $pc://$to");
exit();
}
}
