Well, I tried that, with no luck. This is my actual code:

$width = 150;
$height = 150;
$im = new Imagick('original/' . $filename);
$im->thumbnailImage($width, $height, true);
$im->sharpenImage(50, 1);
$im->setImageBackgroundColor('white');
$im->roundCorners(5, 5, 7);
$im->setImageFormat('jpeg');
$im->writeImage('thumbnail/' . $filename);
$im->clear();
$im->destroy();

I think to do this effectively, you'll need to create two images, as
such (adapting from your code):

<?php
$width = 150;
$height = 150;
$background = 'white';

$im = new Imagick();
$im->newImage($width, $height, $background);

$thumb = new Imagick('original/' . $filename);
$thumb->thumbnailImage($width, $height, true);
$thumb->sharpenImage(50, 1);
$thumb->roundCorners(5, 5, 7);

$im->compositeImage($thumb, Imagick::COMPOSITE_OVER, 0, 0);
$im->setImageFormat('jpeg');
$im->flattenImages();

$im->writeImage('thumbnail/' . $filename);
/* Or display directly to screen
header("Content-Type: image/jpeg");
echo $im;
*/
$im->clear();
$im->destroy();
$cv->clear();
$cv->destroy();
?>

That seems to be the only way I can find to control which colors are used.
