But first of all you need to understand basic html to use this.

How to color text with CSS

You can do this with inline styling or in a external stylesheet
You can write like this
<p style=”color:red;”>Hello</p>
And then it will display like this

Hello

You can also use Hex Values and this is my favorite to use, because almost every design program like Photoshop is using them, and they are easy to find.
<p style=”color:#ed1919;”>Hello</p>
And then it will display like this

Hello

If you want to color specified text in a external stylesheet you can do it with a class.
like this
HTML
<div class=”myclass”>Hello</div>
CSS
.myclass{
color:#ed1919;
}

Hello
If you want want to apply the text color on all text you can use body like this
body{
       color:#ed1919;
}
and if you want to color all of the same type of heading like h1 you can do it like this.
h1{
     color:#ed1919;
}
