jquery css color value returns RGB?

In my CSS file:

a, a:link, a:visited { color:#4188FB; }
a:active, a:focus, a:hover { color:#FFCC00; }

I tried with:

var link_col = $("a:link").css("color");
alert(link_col); // returns rgb(65, 136, 251)

How can I get the HEX code?

*** edit: found the answer here:
Background-color hex to JavaScript variable

Shame on me, could have search a bit better before posting..
