Fig. 4. Decoupling the effects of structure and absorption on scale reflectance.

Fig. 4

(Left) Comparing simulations of scales with the trabeculae removed versus scales with non-absorbing trabeculae. Adding non-absorbing trabeculae to a scale that has none decreased reflectance between 5 and 70% in the visible range (350–700 nm). (Right) Comparing simulations of scales with the ridges removed versus scales with non-absorbing ridges. Non-absorbing ridges contribute a reduction in reflectance between 14 and 58% in the visible range (350–700 nm). For both the ridges and the trabeculae, the structure contributes more to reduced reflectance in the visible range.
