Since you have asked it, here a portion of the actual code that produces Saints in our book page: 
my $step = 0;
my $str = "";
my $color;
my $range = { "min" => 130, "max" => 230, "steps" => 50 };
my $curr;

# ... omissis ...

while($node = $csr->fetchrow_hashref)
{
    # ... omissis ...

    $curr = $$range{max} -
        (($$range{max} - $$range{min})/$$range{steps}) * $step;
    $curr = sprintf("%02x", $curr);
    $color = "#" . $curr . $curr . $curr;
    $str .= "<tr bgcolor='" . $color . "'><td>" # ... omissis ...

    # ... omissis ...
    
    $step++;  
}
