Q:

How to change font color in HTML?

I want to change a paragraph of text to another font color. I have code like this:
<html>
<body>
    <p> Va', pensiero, sull'ali dorate.
       Va', ti posa sui clivi, sui coll,
       ove olezzano tepide e molli
       l'aure dolci del suolo natal!

       Del Giordano le rive saluta,
       di Sionne le torri atterrate.
       O mia Patria, sì bella e perduta!
       O membranza sì cara e fatal!...</p>
</body>
</html>

How can i make it appear in other colors?

A:

You can go several ways of doing this. You can devine your color by predefined colors (see e.g. http://www.w3schools.com/html/html_colornames.asp) or by define the color yourself by hex code (see e.g. http://html-color-codes.info/webfarben_hexcodes/).
Inline CSS
<p style="color:blue">Blue inline CSS font</p>

Internal CSS
Define a style element in your head seaction and all your specified elements will be formatted.
<style>
    p {
        color: blue;
    }
</style>

<p>Blue!</p>

External CSS
Same way as internal CSS except you link a CSS file instead of define the sytle in your head section.
This is the common way of styling with CSS, because the file is cached by the browser, so page load time is can be reduced.
To link you could load a CSS file e.g. by
<link rel="stylesheet" type="text/css" href="style.css">

Old depricated way
<font color="blue">Blue font</font>

or
<font color="#1B29A3">Selfdefined blue text</font>
