Hi Dan
You cannot change the colors used in the tabs but you can add an attribute called tabheight="..." to the <tab/> tag to modify the height.
<tab height="293" left="32" tabheight="60" tabposition="north" top="83" width="647">
<abs id="tab-1" name="Tab 1">
<label height="66" left="78" name="First tab!" style="txt-align:west" top="67" width="212"/>
</abs>
<abs id="tab-2" name="Tab 2">
<label height="66" left="62" name="Second tab!" style="txt-align:west;" top="64" width="212"/>
</abs>
<abs id="tab-3" name="Tab 3">
<label height="66" left="238" name="Third tab!" style="txt-align:west;" top="122" width="212"/>
</abs>
</tab>
If you want more control, it is common to use a radio toggle parameter to control your tab selection and then hide the tabs:
<abs contexttype="opengear" id="_top" keepalive="false" style="">
<meta>
<params>
<param access="1" constraintstrict="false" constrainttype="STRING_STRING_CHOICE" maxlength="0" name="Tab Selection" oid="tab_selection" type="STRING" value="tab-1" widget="radio-toggle">
<constraint key="tab-1">First Tab</constraint>
<constraint key="tab-2">Second Tab</constraint>
<constraint key="tab-3">Third Tab</constraint>
</param>
</params>
</meta>
<tab height="293" left="32" tabposition="none" top="83" width="647">
<abs id="tab-1" name="Tab 1">
<label height="66" left="78" name="First tab!" style="txt-align:west" top="67" width="212"/>
</abs>
<abs id="tab-2" name="Tab 2">
<label height="66" left="62" name="Second tab!" style="txt-align:west;" top="64" width="212"/>
</abs>
<abs id="tab-3" name="Tab 3">
<label height="66" left="238" name="Third tab!" style="txt-align:west;" top="122" width="212"/>
</abs>
</tab>
<simplegrid height="55" left="31" rows="1" top="22" width="646">
<param expand="true" oid="tab_selection" runtasksonload="true" showlabel="false" style="style:navigationButton;">
<task tasktype="ogscript">ogscript.reveal(this.getValue());</task>
</param>
</simplegrid>
</abs>
