Interesting Observation?

I have noticed that the dark green Serendip arrows always appear more readily for me.  However, when I glanced at Grobstein with them in the background, it was the yellow arrows I saw.  The yellow shirt Grobstein was wearing might have contributed to this effect.  The environment altered my perception of the ambiguous figure.
