The uppercase version is white lettering on a black background – similar to the originals. On the lowercase keys is a set of initials that are black on white with a black border.
Since the inverted triangles resemble pennants, there's a solid black blank on the left parenthesis key and a outlined blank one on the right parenthesis key. In this way, the initials could be used for monograms or interspersed with the blanks to form short banner messages.
