It is not easy for the beginners to make sense of the colour codes that are used in HTML. The HTML colour codes are been written in such a way that it has some specific reason. The colour codes of the HTML are been put together and are composed of the six hex numbers which would even represent the possibility of 16.7 million colour combination. The colour codes of the hex are been built on RGB colour model, where R is red, G is green and B is blue. In the typical HTML code it would look like #FFFFFF and it breaks down. Here in ‘#FFFFFF’, the initial two digits would represent the colour ‘red’. The next set of two digits of ‘#FFFFFF’ would represent ‘green’. The final and the third set of the two digits of ‘#FFFFFF’ would represent ‘blue’.
In the general mathematics the hex or a hexadecimal is the numeral system that has the base of the number 16 which is normally written by using the symbols from 0 – 9 and even A – F. the numbers from 0 – 9 would have the same value even in the decimal system but, it would start from the letter A, the value starts increasing till it reaches the value 16. A is equal to 10, B is equal to 11 and this continues till it reaches F, as F is equal to 16. This would be according to the hexadecimal system.
The colour model of RGB would be similar to the colour model of the HTML as it can represent the total of 16.7 million colours. It would vary among the colours green, red and blue. It would be possible for anyone to show the 16.7 million colours. The RGB value would be represented any of the numbers that is between 0 – 255. The set of the RGB values for white colour would be 255, 255, 255 for instance. Here you would also know how to establish the hex numeral system along with the numbers that are ranging from 0 – 16. After this you just need to combine both the hex numbers. You can even represent any numbers that is between 0 – 255. As you could even see that the colour codes of HTML and RGB represents some colour model.
Many years ago the monitors had the capacity to display only 256 colours. But even these monitors were very popular when HTML was put together. It would even be necessary to put the list of colours together as the web designers can also make sure that the given monitor could display it properly. The result of this would be the ‘web safe colours’. This ‘web safe colour’ palate would contain 216 colours. It would always be the good practise to take the standard colours over the board, but now it is not necessary to stick for the ‘web safe colours’. This rule might be excepted while developing the websites for PDA’s and even the mobile phones.
