I have an idea on how to do this. Could someone confirm whether this is a
good approach?
function grayscaletohex ($val)
{
$n = ($val * 255) / 100; // convert from range of 100 to
range of 255
$h = dechex($n); // convert decimal to hex
$results = $h.$h.$h; // create 6 digit browser color
string
return $results;
}
