Are there any best practices for generating color codes dynamically in PHP without manual input?

Generating color codes dynamically in PHP without manual input can be achieved by using the `random_int()` function to generate random RGB values. These values can then be formatted into a hexadecimal color code and used in your application. It's important to ensure that the generated color codes are unique and visually appealing.

// Generate random RGB values
$red = random_int(0, 255);
$green = random_int(0, 255);
$blue = random_int(0, 255);

// Format RGB values into hexadecimal color code
$colorCode = sprintf("#%02x%02x%02x", $red, $green, $blue);

// Use the generated color code in your application
echo "<div style='background-color: $colorCode; width: 100px; height: 100px;'></div>";
