What version requirements should be considered when using image functions in PHP for better color representation?

When using image functions in PHP for better color representation, it is important to consider the version of PHP being used. The GD library, which is commonly used for image manipulation in PHP, has different capabilities and features depending on the PHP version. It is recommended to use PHP 7 or higher for better color representation and improved image processing capabilities. 

// Check if the GD library is enabled and the PHP version is compatible
if (extension_loaded('gd') && version_compare(PHP_VERSION, '7.0.0', '>=')) {
    // Your image processing code here
} else {
    // Display an error message or fallback option for older PHP versions
    echo 'This feature requires PHP 7 or higher with the GD library enabled.';
}
