HTML colors are specified with predefined color names, or with RGB, HEX, HSL, RGBA, or HSLA values. In HTML, a color can be specified by using a color name, and HTML supports 140 standard colors.
Background color can be set for HTML elements.
Ex: <h1 style="background-color:DodgerBlue;">Hello World</h1>
<p style="background-color:Tomato;">Lorem ipsum...</p>
<p style="background-color:Tomato;">Lorem ipsum...</p>
Texat can also be colored.
Ex: <h1 style="color:Tomato;">Hello World</h1>
<p style="color:DodgerBlue;">Lorem ipsum...</p>
<p style="color:MediumSeaGreen;">Ut wisi enim...</p>
<p style="color:DodgerBlue;">Lorem ipsum...</p>
<p style="color:MediumSeaGreen;">Ut wisi enim...</p>
Color borders are also something that can be done in HTML

<h1 style="border:2px solid DodgerBlue;">Hello World</h1>
<h1 style="border:2px solid Violet;">Hello World</h1>
<h1 style="border:2px solid DodgerBlue;">Hello World</h1>
<h1 style="border:2px solid Violet;">Hello World</h1>
