Will CSS ever be programmable?

Do you think CSS will ever get to the stage where we can use variables
and pro grammatically set values, like:

colour1:=red;
colour2:=blue;
colour3:=white;

body {background-color:colour3; color:colour2; border: thin solid colour1}

etc

???

Something like this, perhaps:

<http://cfaj.freeshell.org/www/prgcss.shtml/black/red>

What would be the point? You would be just adding a line of unessacary code

I will extend the example to make it more apparent:

colour1:=red;
colour2:=blue;
colour3:=white;

body {background-color:colour3; color:colour2; border: thin solid colour1}
h1 {background-color:colour2; color:colour3;}
h2 {background-color:colour3; color:colour1;}
etc

....you could change the entire site colour scheme more easily.
....it would save you minutes!

Any decent editor has a S&R feature

Search: color:blue
Replace: color:red

Only takes a few seconds

Btw, this is off topic in alt.html.critique, crossposted and follow-up
set to alt.html

This can already be done using a combination of server-side programming
and CSS. Say, PHP, perhaps?

example CSS file, "site.css.php":
---------------------------------
<?
header("Content-type: text/css");
$color1="red";
$color2="blue";
?>
p {
background-color: <?= $color1 ?>;
color: <?= $color2 ?>;
}
---------------------------------


Just an example.

Wouldn't that cause the stylesheet to be retrieved from the server again
and again for every page?

come again? How would that happen?

All you have to do to use my proposed CSS+PHP stylesheet is call it
normally in the header:

<LINK href="style.css.php" rel="stylesheet" type="text/css">

Without counter measures the stylesheet would be generated by PHP each
time it is called, generating a different file timestamp, thereby
thwarting cachebility.
