PHP color.php
list($coords) = array_keys($_GET);
$coords = explode(',', $coords); // Easier way...?
$im = imagecreatefrompng('colormap.png');
$color = imagepixelat($im, $coords[0], $coords[1]);
I wouldn't do it like this, though. I'd use Javascript.

This is a very Bad Idea[tm], because it's going to generate
16,777,216 lines that the browser needs to receive, parse, and
display. This is going to be over 2,516,582,400 bytes (yes, 2.5GB!)
of data to be served. There are several better ways of doing it,
including using an HTML image map that has all of the colors laid-out
by pixel coordinates, reducing the number of colors you want to
display, using Flash, or any number of alternatives.
In any case, here's the code:
R: ".$_GET['r']."\n";
echo "G: ".$_GET['g']."\n";
echo "B: ".$_GET['b']."\n";
echo "\n";
}
}
$newline = 63;
for($i=255;$i>0;$i--) {
for($j=255;$j>0;$j--) {
for($k=255;$k>0;$k--) {
echo "";
echo "X";
if($newline === 0) {
echo "\n";
$newline = 63;
} else {
echo "\n";
$newline--;
}
}
}
}
?>
It's also available to view here (but the demo is limited to save
my server from Yahoo! Slurps, Google grabs, etc.):
