You should be able to calculate how many colors we can represent using the available number of hex digits or binary digits. You must also be able to reason why we prefer to use hex representation over binary.

Here is a summary, for further reading read your book or

Summary:

There are many ways of representing an individual color. For a few colors, some commands in Active Worlds support the use of pre-defined color names, but for the rest of them an alternative method is needed.

Hexadecimal RGB color values represent the amounts of Red, Green, and Blue light necessary to simulate the color with most standard televisions or computer monitors.

Each of the three parts is represented as a two digit hexadecimal value in the range of 00 to FF, so the total hexadecimal RGB range is from 000000 to FFFFFF and includes a total of 16777216 distinct color representations. (1000000 hexadecimal = 16777216 decimal.)

This page lists a few of them for you to choose from, to help you get a feel for the process of using hexadecimal RGB color values. Most of the tables listed on this page contain groups of colors based on the pre-defined color names and are provided here with their hexadecimal RGB values for your convenience, for use with action commands such as sign, color, and light.
