The "font" tag is in current versions of HTML, but in the future it will be replaced and incorporated with the paragraph <p> tag.
<font> by itself does nothing. To make it do something, you have to add one or more extras.
<font colo="color"> or <font color="xxxxxx"> will change the color of all text until the </font> tag.
Quotation marks are REQUIRED.
The basic color names can be used, including red, blue, black, brown, orange, pink, purple, grey, white, silver. Any of 140 different established colors can be used as well, this link shows them, with their HEX numbers for referencing.
<font color="red">Red Text</font>Red Text
<font color="blue">Blue Text</font>Blue Text
Now to get special colors, use the hexideximal format. xxxxxx
First two are hex 00 throug FF or 256 shades or red.
Second two are hex 00 through FF or 256 shades of green
Third two are hex 00 through FF or 256 shades of blue.
You can do the math to work out 16.7 million different colors.
All 000000 is black or the absense of all color. FFFFFF is white or the sum of all color.
If each "pair" is the same, it will be one of 256 shades or pure grey.
404040 is dark grey, 808080 is medium grey, C0C0C0 is light grey.
<font color="FF0000">Red Text</font>Red Text
<font color="00FF00">Green Text</font>Green Text
<font color="0000FF">Blue Text</font>Blue Text
To make red darker
<font color="C00000">Darker Red</font>Darker Red
<font color="800000">Dark Red</font>Dark Red
<<font color="400000">Very Dark Red</font>Very Dark Red
To make red lighter, add equal green and cyan.
<font color="FF4040">Light Red</font>Light Red
<font color="FF8080">Pink</font>Pink
<font color="FFC0C0">Light Pink</font>Light Pink
There are literally 16 million colors, I cannot possibly explain them but experiment with them.
