The few colors terms:

How screens diplay colours

As discussed in the section above, what are colours?, a computer monitor is made up of thousands of tiny little red, green and blue dots which are grouped three and three. These little dots are close together-- so close that we don't really see them as dots, but rather our eyes mix them up to form one homogenous colour.

All colours in the spectrum can be generated with this system of dots. For instace, if the red and green dots are shining at 100% their strength, while the blue not lit at all, you will see the result as a pure yellow colour. Each of the three dots can have any value from 0 to 255, which means that the total number of possible colours is 256*256*256 = 16,777,216.

Any colour can be represented by a specific combination of three numbers. The yellow mentioned before would have the number 255, 255, 0. The first number represents the red dot, the second represents the green dot, and the last represents the blue. Therefore, a pure blue colour would then be 0, 0, 255. The lower the number, the less that color dot is lighted. For instance, by lowering the number for the blue dot-- to the colour identified as 0, 0, 100-- you can produce a darker blue. White is produced by the combination of the highest amount of all three colours, so the code for white is 255, 255, 255. Black, on the other hand, is produced by a lack of other colours, so the code for black is 0, 0, 0.

Web-safe colours.
Anyone who has done any sort of web page has probably heard of the web-safe colours. Web-safe colour is a rather debated issue among web desingers these days. Many firmly believe in using only these colours, while others feel they can allow themselves to use colours which are not regarded as safe.

What are web-safe colours?
Web-safe colours are somewhat of a remainder from the early years of the web, back when a normal screen could only display 256 colours. Back then, there was a need to worry about consistency in how browsers displayed the colours. The system is made up of some 40 colours, for menus and such, and the remaining 216 colours could be used to display the actual web pages.

Now, 216 colours might sound like quite a bit, but the problem is that no aesthetic considerations were made when these colours were decided, but rather they are based solely on mathematical formulas. To be more exact, the web-safe colours are what you get when you use 0%, 20%, 40%, 60%, 80% and 100% of the three different primary colours, and then mix these in every possible combination.
