# Use Abbreviated Hex Code

---
## Problem Explanation
Red, which is `#FF0000` in hex code, can be shortened to `#F00`. That is, one digit for red, one digit for green, one digit for blue.

This reduces the total number of possible colors to around 4,000. But browsers will interpret `#FF0000` and `#F00` as exactly the same color.

```html
<style>
  body {
    background-color: #F00;
  }
</style>
```
