You should see three svg logo images with green fill above here.
If any of the logos are shown in orange that means the browser failed to access the DOM of the referenced svg resource.
From left to right we have <object>, <embed> and <iframe> that all reference the same svg file.
The script gets the referenced svg document either with
getSVGDocument() and then sets the fill color
to lime green.
