This test creates an SVGColor object and verifies that the intial data is all zero. It then modifies the red, green, and blue attributes. To pass, the resulting attributes should be as expected should be correct, and when this happens the text changes from 'failed' to 'passed'

Note that, since the test does not insert this object into the document, it is not displayed. The test simply verifies that the object has been created correctly.
