Question

can any one has answer for this question..? let's see how many solution i get.

Answer 1

You can surely use the color by its name but tell me how many color names you remember? 10? 20? 50?
Well it is much harder to remember 256x256x256 color names for a normal human being.
So, we use hexadecimal codes or RGB codes.
However, there are 16 basic color names are predefined in HTML which can be used by their names.
Must check it out on Google.

Answer 2

It isn't 'necessary', but it's useful: most of coders think hexadecimal is more readable than decimal :P ( joke, but true for rgb colors ;) )
And not only you can use named color, but also rgb or rgba decimal system, hsv and others:

Answer 3

Color names aren't precise. There's no rule that states how a browser should render some of the weirder color names. Example "cherry-black": Firefox may render it as #330000 while Chrome renders it as #220000. Two different colors with the same descriptive name. That's why web designers prefer precise color definitions:
hex #FF0000
or rgb(255,0,0)
or hsl(0,100%,50%)
