I think the photos are in black-and-white; if so, the nib will be gold. The nib is a specialty nib for writing kanji characters: it is narrow on the downstroke and wide on the crossstroke. If you use just the tip, in an extreme writing angle, it writes a very narrow line. I have one; I really like it (and have joined this drop), but it is not for everyone.
