Basic Imagick::getColor() usage

<?php
 
//Create an ImagickPixel with the predefined color 'brown'
$color = new ImagickPixel('brown');
 
//Set the color to have an alpha of 25%
$color->setColorValue(Imagick::COLOR_ALPHA, 64 / 256.0);
 
$colorInfo = $color->getColor();
 
echo "Standard values".PHP_EOL;
print_r($colorInfo);
 
$colorInfo = $color->getColor(true);
 
echo "Normalized values:".PHP_EOL;
print_r($colorInfo);
 
?>
