I've hit a bit of a weird issue in Safari in regards to setting a js cookie. The cookie itself is just a rgb colour value, which gets set using .click(), and is working fine in Chrome and Firefox, yet in Safari the value of the cookie is incomplete, showing up as rgb(193 instead of rgb(193, 184, 76) as the other browsers do.

The jQuery function I'm using to set the cookie is:

$('.project_link a').click(function() {
    var link_colour = $(this).css("color");
    document.cookie = "colour="+link_colour+";expires=;path=/";
});
