Events List alternating color

You can try this one:

e.g.

In your formats/layouts > events format:

Default event list format header:
<table cellpadding="0" cellspacing="0" class="events-table" >
    <thead>
        <tr>
			<th class="event-time" width="150">Date/Time</th>
			<th class="event-description" width="*">Event</th>
		</tr>
   	</thead>
    <tbody>

Default event list format:
<tr>
			<td>
                #_EVENTDATES<br/>
                #_EVENTTIMES
            </td>
            <td>
                #_EVENTLINK
                {has_location}<br/><i>#_LOCATIONNAME, #_LOCATIONTOWN #_LOCATIONSTATE</i>{/has_location}
            </td>
        </tr>


Default event list format footer:
</tbody></table>


Then in your theme style.css:
table.events-table thead {
 background-color: black;
 color: white;
 text-indent: 14px;
 text-align: left;
}

table.events-table tbody tr:nth-child(odd) {
 background-color: rgba(0, 255, 0, 0.1); /* green, 10% alpha */
}

table.events-table tbody tr:nth-child(even) {
 background-color: rgba(255, 0, 0, 0.3); /* red, 30% alpha */
}
