## Description
|
|
<section id='description'>
|
|
Many people feel overwhelmed by the possibilities of more than 16 million colors. And it's difficult to remember hex code. Fortunately, you can shorten it.
|
|
For example, red's hex code <code>#FF0000</code> can be shortened to <code>#F00</code>. This shortened form gives one digit for red, one digit for green, and one digit for blue.
|
|
This reduces the total number of possible colors to around 4,000. But browsers will interpret <code>#FF0000</code> and <code>#F00</code> as exactly the same color.
