Tryed Imagick::quantizeImage() which needs an Imagick::Colorspace as second argument. Strange thing is that every colorspace i choose, the return keys of an array are still r/g/b  instead of colorspace named keys like h/s/b or l/a/b for example when reading the colormap with Imagick::getColors().

Reproduce code:
// this->image comes from the class constructor
// -> $this->image = new Imagick($image);
function getColors()
    $this->image->quantizeImage( 30, Imagick::COLORSPACE_HSB, 0, false, false );

    $it = $this->image->getPixelIterator();

    while( $row = $it->getNextIteratorRow() )
	    foreach( $row as $pixel ) $this->colors[] = $pixel->getColor();


Expected result:
Expected different return keys when changing the colorspace constant. Unfortunately i don't know which stack expresses what if the colorspace isn't RGB. Either i don't know if the problem is in quantizeImage() or getColors().

Try using the ImagickPixel::getColorAsString() method. You should use that for colorspaces other than RGB(A).
