changes color of skipped functional tests

Changes the color of skipped functional tests to the default text color of the terminal. This will make skipped tests easy to read on the majority of background colors rather than the original grey color (hard to read on dark backgrounds) and the proposed yellow change (hard to read on white backgrounds)
