Flowers produce variations in color saturation by arranging petals at oblique and varying angles

摘要: Large color variations can be observed across the face of a flower even when individual petals are same color. We investigated whether these could explained by model that incorporates multiple reflections light between and transmissions through before returns to observer. The three flowers we selected for study exhibited large intact but had no significant observable difference in saturation single petal or were removed from flower. used spectroradiometer measure spectrum faces petals. measured spectra all consistent with proposed model.
