Setting of colors used in many html tags, e. g. in <body>, <font>, <hr>, <table> and some other. You may use two methods for color setting.
1. Set the color by color name. Some colors have a names which all modern browsers are support correctly but use of color names is not recommended because some old browsers can't recognize it. There are table of 16 standard colors which supports by all browsers.

2. Set the color by it RGB value. All colors which you may see on your display are a combination of three main colors - red, green and blue (RGB). Value of every these colors may change from 0 (color is absent) to 255 (maximal intensity of color).
For example, to set yellow color, it is necessary to mix red (255) and green (255) colors without blue (0).
To use this method in HTML you must set the color in hexadecimal value. For example, hexadecimal value of the yellow color is FFFF00. You must put # before color code.
This method is recommended because with this methods you may set value of any color and all browser will show it correctly.

Examples

<font color="red">Red letters</font>

<font color="#9932cc">Recommended method of color setting.</font><br />
<font color="DarkOrchid">Non-Recommended method of color setting.</font>

Recommended method of color setting.
Non-Recommended method of color setting.
In this example, as in previous, you can see that color of a both string are identical. But you can see it if only you have a modern and popular browser (Internet Explorer, Opera, Firefox etc). Old and rare browsers can't show color of second string. What color will have this string? It knows only browser's developers. So, use a hexadecimal value to set the "non-standard" color.
If you don't know how translate color number from decimal to hexadecimal number, you may use a special soft, e.g. Adobe Photoshop, PaintShopPro, or online service e.g. www.colorschemer.com/online.html
