Hi monks,
For each iteration of my foreach loop, I want a different color...
but I am getting error

Can't use string ("lightblue") as a SCALAR ref while "strict refs" in use at a.pl line 184, <STDIN> line 2.

I am using a subroutine 
sub coloring{
  my @color= qw(  lavender lightblue honeydew);
  my $color_no=int(rand($#color));
  return $color[$color_no];
}

In main code, calling my sub 
my $lavender=$im->colorAllocate(230,230,255);
my $lightblue=$im->colorAllocate(173,216,230);
my $honeydew=$im->colorAllocate(240,255,240);
while(@ary) {
       my $genecolor= coloring ();
       $im->filledRectangle($X1,$Y1-20,$X2,$Y2,$$genecolor);
            }

How to deal with $$genecolor issue?? Pl help/suggest.
