You could use a hue-rotate filter, or you could fix the colors as suggested above. Probably more compatible to change the colors to what you need, but in any case, here's an example of the filter variant:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<filter id="h200" x="0" y="0" width="1" height="1">
<feColorMatrix type="hueRotate" values="200"/>
</filter>
<image xlink:href="http://imgur.com/D9aFo.png" width="207" height="46" filter="url(#h200)"/>
</svg>
You can see it live here if you use a browser that supports svg filters, e.g Opera or Firefox.
