"The Whole world,
as we experience it visually,
comes to us through the mystic realm of color."

Color

-It is very important to think about colors when designing a web page
-You want to make sure that you use colors that look good together
-Changing colors on your webpage is very simple, you can change the text or background color
-To change your background color you just type <body bgcolor= "#ffff00">
-To change the color of your text just add this onto your back ground color tag:
<text= "#ffff00">

Primary and Secondary Shades of Light

-the primary colors of light are red, green and blue
-When these color wavelengths are combined they produce white light
-Secondary colors of light result from combinations of primary colors
-Some examples of Secondary colors are yellow, magenta, and cyan
-white light is a mixture of all of the colors together reflecting off of a surface
-when an object apears black that means that all of the colors are being absorbed into a surface
-below are some pictures of primary and secondary colors

       

Tertiary Colors

-there is also one other category of color which is tertiary
-tertiary colors can be created by mixing a primary color with a secondary color
-unlike primary and secondary colors, tertiary colors are not
represented by one firmly established name
-however some examples of popular tertiary colors are brown and grey
-here is a chart of some tertiary colors:

RGB Color Model

-this model uses red, green, and blue light to create an array of different colors
-the main use of this model is for:
      -sensing, representation, and display of images in electronic systems
-it has also been used in conventional photography
-RGB stands for "red, green and blue"
-RGB is a device-dependent color space which means that different devices detect or reproduce a given RGB value differently
-here is a picture of an RGB model:


HSV Color Model

-it is one of the most common cylindrical-coordinate representations of points in an RGB color model
-it rearranges the geometry of RGBin a attempt to be more accurate
-it was developed in the 1970's
-HSV stands for "hue, saturation, and value"
-it is some times called HSB (B for brightness)
-the purpose is to aid selection, comparison, and modification of colors by organizing them into more useful geometrical shapes
-here is one view of the HSV color Model:

Color Blindness

-color blindness is the inability to percieve some colors that others can view
-those people who have color blindness often see websites differently then they are designed
-many people who design web sights often take the needs of color blind people into their consideration
