Pulsating colors in javascript

I'd like to have some text pulsate between red and black. Figured I'd use jQuery UI's animate function to do so. Seems simple enough... something like:

function pulseRed() {
    $('.pulsing').animate({ color: "red开发者_运维技巧" }, 1000, pulseBlack);
}
function pulseBlack() {
    $('.pulsing').animate({ color: "black" }, 1000, pulseRed);
});

My concern is how efficient this is. If I have a lot of text in different places to pulsate, should I instead somehow alter the CSS stylesheet rule for .pulsing? Is it safe to have an infinite loop between functions like that or am I going to get in trouble for stacking too many function calls?

I'm already using jQuery and jQuery UI, so I don't mind at all using the animate color mechanism above... but if there's a better solution I'd love to hear it.

If you are using jQuery UI you might want to consider using the animated toggle class instead, if you wrapped that in a setInterval() function you could reduce it to one line, and store the formatting in the CSS rather than the javascript.
