Fig. 4: Differential pigment responsiveness.

a Independent sequential pigment fluid dispersal/retraction cycles as a response to measured local light intensity behind each cell. Measured value of light intensity drives negative feedback response for each digitally-driven pump. b Image captures from Supplementary Movie 5, showing localized responses in five independent positions across the facade over time. Scale bars are 10 cm. c Light intensity as a function of time for five different sensors. d Image captures from Supplementary Movie 6 to demonstrate differential pattern control over time. Scale bar is 10 cm. e Differential pigment fluid response across all sixteen cells for five independent sequences. Scale bar is 7 cm. f Second sequence from (e). g Schematic of experiment in (e, f).
