Fig. 3.

Color change in scale iridophores is driven by the tilting of crystals. (A) Iridophores are typically blue before NE treatment (Left), red 4 min after NE addition (Middle), and finally yellow 7 min after NE addition (Right) (these two shifts were seen in 6 out of 10 scales from three different fish). Insets show representative colors for each time point. (B) A schematic showing the X-ray diffraction experimental setup, where a change in the tilt orientation of crystals results in a change in the (Δω) of the diffraction spot. (C) Pseudotemporal colored representation of 32 diffraction spots over a 7-min period following NE addition. (Scale bar, (A) 10 µm.)
