[magick-users] unrecognized color given as HSL tuple

[Petr Gajdusek]

Hi, I am new to imagemagick and I try to colorize an existing image, I
specify the color as HSL tuple:

convert -fill "hsl(308,47,83)" -colorize 10  a.png b.png

but result is:
convert: unrecognized color `hsl(308,47,83)'.

What I am doing wrong? 

Thanks.
