1. THE COLORS OF LIGHT RED, GREEN and BLUE
Don’t think of red, green and blue as primary colors – to a computer, they represent light.
Placing one light (color) on top of another creates white, not black – black is the absence of light.
Red, green and blue are ADDITIVE COLORS.

2. COLOR CODING There are five color options from which to choose:
Background
Font
Links
Active Links
Visited Links
All are created by using a combination of six numbers or letters: (black) up to FFFFFF (white). There are 216 browser-safe color combinations.

3. CODING WITH HTML CODE Background <BGCOLOR=“#FFFFFF”>
Font <TEXT=“#000000”>
Links <LINK=“#6666FF”>
Active Links <ALINK=“#FF0000”>
Visited Links <VLINK=“#993399”>

4. BIT (COLOR) DEPTH
Bit depth refers to how many colors can reside in an image.
8 bit = 256 colors
16 bit = 64,000 colors
24 bit = 16.7 million
32 bit = Wow!
The amount of color you can view depends upon the size of your browser. Less powerful browsers compensate for large graphics by DITHERING (fooling the eye).

5. GIF or JPG? There are two basic photo formats for the Web:
GIF (Graphic Interchange Format) Uses lossless compression
JPG (Joint Photographic Experts Group) Uses lossy compression
They are NOT interchangeable.
GIF is for line art (cartoons, drawings, etc.) Transparent images Animation
JPG is for photographs
