When you're using an image with an alpha channel (for example a transparent png), a value of 1.0 will return a completely transparent image, but a value of 1 works just fine.

simplest example <?php $nombre = '001-4-0043.jpg'; $img = new Imagick($nombre); $img->negateImage(false); //$pixblu = new ImagickPixel('#000040'); $img->colorizeImage('#0000b0',1.0); header('content-type: image/jpeg'); echo $img; ?>
