HTML - 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

ColorHexaColorHexColorHexColorHex
aqua#00FFFFgreen#008000navy#000080silver#C0C0C0
black#000000gray#808080olive#808000teal#008080
blue#0000FFlime#00FF00purple#800080white#FFFFFF
fuchsia#FF00FFmaroon#800000red#FF0000yellow#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.

Decimal

0123456789101112131415

HEX

0123456789ABCDEF

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

An example of hexadecimal code would be:

htmlbgcolor="#FFFFFF"

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.

htmlbgcolor="#CC7005"

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

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

*0FF*3FF
*6FF*FFF
