Color codes

There are three different ways of defining a color. The easiest way is to name the color in English. For example: black, white, red, green and blue. I have put together the names of the color which are supported in HTML

Color Hexa Color Hex Color Hex Color Hex
aqua #00FFFF green #008000 navy #000080 silver #C0C0C0
black #000000 gray #808080 olive #808000 teal #008080
blue #0000FF lime #00FF00 purple #800080 white #FFFFFF
fuchsia #FF00FF maroon #800000 red #FF0000 yellow #FFFF00

HTML – The RGB color system

This color code is not recommended because Internet Explorer is the only browser which supports RGB values in HTML.

RGB is a shortcut from : Red, Green, Blue. Every single color of these can take any value between 0 (which doesn’t matter) and 255 (the full proprieties of that color).I have put together in the way of how you write RGB colors. If you use a browser which is not Internet Explorer you will have no result.

bgcolor=”rgb(255,255,255)” White
bgcolor=”rgb(255,0,0)” Red
bgcolor=”rgb(0,255,0)” Green
bgcolor=”rgb(0,0,255)” Blue

HTML – The hexadecimal color system

The hexadecimal system is pretty hard at first look but with all this we assure you that once with the time passing, and with a bit of practice, you will understand it fully. The hexadecimal color system is the standard system for all the web browsers. Is confident and compatible not only in web applications.

The hexadecimal system is a representation of 6 color characters. First two characters (RR) represents the red value, and the next two (GG) are green, and the last two (BB) are blue.


HTML – Color code – Breaking the code

The next table shows , more precisely, how the letters are integrated in the hexadecimal
system, making the combination possibilities bigger.


0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15


0 1 2 3 4 5 6 7 8 9 A B C D E F

In this way the possibilities are bigger and the system can have 16 values.

An example of hexadecimal code would be:


The “F” letter is the maximum value whom the system can take. When a browser sees this code it will show the white color.In case you want to find out the numerical value of this color we have the next formula:

html(15 * 16) + (15) = 255

The formula is very simple. We take the first value of the “F” or 15 and is multiplied with 16 and we add to the second value 15. The result is 255, the maximum value whom a primary color can have.


CC(RR - Red)
(12 * 16) + (12) = 204

70(GG - Green)
(7 * 16) + (0) = 112

05(BB - Blue)
(0 * 16) + (5) = 5

True colors

The hexadecimal system is very used for creating pages. This is compatible with the majority of the browsers, in this way the displayed colors for a web page will not be changed. As an assurance, use the colors true colors like :”#0011EE”, “#44HHFF”, or “#117788”. This type of colors will not be changed in a browser.

Here we have a list of the true colors

*000 300 600 900 C00 *F00
*003 303 603 903 C03 *F03
006 306 606 906 C06 F06

*00F 30F 60F 90F C0F *F0F
030 330 630 930 C30 F30
033 333 633 933 C33 F33

090 390 690 990 C90 F90
093 393 693 993 C93 F93
096 396 696 996 C96 F96
099 399 699 999 C99 F99
09C 39C 69C 99C C9C F9C
09F 39F 69F 99F C9F F9F
0C0 3C0 6C0 9C0 CC0 FC0
0C3 3C3 6C3 9C3 CC3 FC3
0C6 3C6 6C6 9C6 CC6 FC6
0C9 3C9 6C9 9C9 CC9 FC9
*0F0 3F0 *6F0 9F0 CF0 *FF0
0F3 *3F3 *6F3 9F3 CF3 *FF3
*0F6 *3F6 6F6 9F6 *CF6 *FF6
0F9 3F9 6F9 9F9 CF9 FF9

We recommend to stick to these 216 “web-safe”. However, 8-bit color displays were much more common when the 216-color palette was developed than they are now. Anyway, it has been discovered that only 22 of the 216 colors in the web-safe palette are reliably displayed without inconsistent remapping on 16-bit computer displays.

We attached here a table with these 22 really safe colors:

*000 *F00
*003 *F03
*00F *F0F
*FF0 *FF3
*CF6 *FF6
*0F0 *6F0
*3F3 *6F3
*0F6 *3F6
*0FC *3FC
*0FF *3FF
