If the yellow kudos bar in your profile clashes with your skin, you can change the colour so it fit's in better. Simply add the following to your custom css

span.status-rank {
background: #272C7B;
}

Or you can choose to have a gradient or other background image of your own, so instead use this

span.status-rank {
background: #272C7B url(http://www.website.com/images/rank-gradient.gif) center no-repeat;
}

Just make sure your image is long enough and wide enough in case you fill the bar up to the top!
