You are on the right track Tony, though there are multiple ways of  
achieving this.

Here is one:

If you WORepetition wraps a tr then make the tr dynamic (turn it into  
a WOGenericContainer) then give it an "id" attribute and bind that to  
a method that returns the name of the css selector for the coloured  
background or null (if the method returns null, the "id" will not be  
included in when the WOGenericContainer is rendered).

ie:

.html:

<table><webobject name="GenericContainer1"><td>Cell</td><td>Cell</ 
td><td>Cell</td></webobject></table>

.wod:

GenericContainer1: WOGenericContainer {
	elementName = "tr";
	id = rowColourId;
}

.java:

public String rowColourId() {
	String result = null;
	if (colourRowCondition()) { // whatever condition should trigger a  
coloured row background.
		result = "rowColour"
	}
	return result;
}

.css:

#rowColour {
	background-color: #eee;
}
