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;
}

Subject: [PHP] Convert a grayscale value to a #RRGGBB hex value
Anyone know how I might convert a grayscale value, from between 0 to
100, to hex, such that 0 (black) would be returned as
#00, and 100
(white) as #FF? For example...
function grayscaletohex ($val) {
$hex = $val ... [ a simple operation ]
return $hex;
}
Thanks.
...Rene
