rich:tooltip is not showing mentioned color

[Abhra Kar]

Hi I have this code ---------

<h:graphicImage id="image199" url="/images/tokeep/info10.png" rendered="true" style="border:0;vertical-align: middle;">
<rich:toolTip>
<h:outputText value="#{iconTextBundle['elements.service.elements.secondary.usage.manager']}" style="color:#000000;" />
</rich:toolTip>
</h:graphicImage>

The color is black , but in output the text is coming in white color.
please inform why the color is not coming in black .

Thanks in advance.
