You can build a simple color gradiant by doing something like:
my @to_color = qw/ one two three four five /;
my @colors = &get_gradients(scalar @to_color);
sub get_gradients {
my $number = shift;
my $interval = 0xff / ($number - 1);
my (@c, $i);
push(@c, sprintf("%02x", $interval * $i++)) while $i < $number;
return @c;
}
Building an HTML table out of that information is left as an exercise for the reader. See
CGI.
