How To Specify (Override) JQuery Icon Color

Question

I've been making good use of the jQuery icons in my web app, but have come to a point where I would like to use a color that I'm not able to achieve by default. I'm currently using the "State Street" theme, which primarily uses green. But I have a red box with white text, and would like to use an icon that is white as well. There are white icons that are supplied with the theme, but they only get applied when the icons are inside a div (or some other container) that has a class of "ui-state-focus". This will make the icon white, but will change the background color to green, which I want to leave as red.

Is there any way (most likely via CSS) to override what background image jQuery uses for the icons, so that I can use a different color?

Thanks.

CLARIFICATION: I guess it would help for me to post the html I'm currently working with:

<!-- currently produces a default 'grey' icon color -->
<!-- this b/c no jquery ui class (like ui-state-focus) given for errorMessage div -->
<div id="errorMessage">
    <span class="ui-icon ui-icon-alert" style="float: left"></span>
    Only 1 Activity can be added at a time 
</div>

I also have CSS:

.dialog #errorMessage
{
    /*display: none;*/
    background-color: #CC3300;
    color: #FFFFFF;
    font-weight: bold;
    padding-top: 3px;
    padding-bottom: 3px;
    vertical-align: bottom;
    bottom: auto;
    font-size: .80em;
    width: 100%
}

"display: none" is currently commented out so I can see it. I do have it set up to fadeIn on error catch. Thanks again for the help.

Answer 1

You can overwrite the icons with the following CSS:

.ui-icon
{
    background-image: url(icons.png);
}

You can download the icon png file in any color you like. Just change the color part in the following url:

http://download.jqueryui.com/themeroller/images/ui-icons_*COLOR*_256x240.png

For example, if you want Red icons, and Cornflower Blue icons, the URLs you need are:

http://download.jqueryui.com/themeroller/images/ui-icons_ff0000_256x240.png
http://download.jqueryui.com/themeroller/images/ui-icons_6495ED_256x240.png

etc.

(but don't use the URL as a CDN, be nice and save the files locally)

SELF-ANSWER: Specified the background-image URL myself to be the file that uses the white icons. So I added a few lines to my CSS file:

.dialog #errorMessage .ui-icon
{
    background-image: url(../../CSS/themes/custom_green/imag/ui-icons_ffffff_256x240.png);
}

This essentially overrides the background image that the default jQuery css file wants to use for the icon, and achieved the color that I wanted. Of course this only worked because a white icon .png file was included with the theme. If I wanted some crazy color, like purple, I would have needed to create my own icon(s). Note that I needed to lengthen the URL in my own CSS file versus the URL that is specified in the jQuery CSS file, because they're located in two different places in my source.

Use built-in icon generator for icon color #00a300 # dark green

.ui-icon
{
    background-image: url(http://jqueryui.com/themeroller/images/?new=00a300&w=256&h=240&f=png&fltr[]=rcd|256&fltr[]=mask|icons/icons.png) !important;
}
