通过二极管阵列光谱仪在 310 至 730 nm 范围内测量羽毛的光谱反射率。在许多羽毛中，紫外线 (UV) 反射增加了可见光范围内的反射，从而导致它们呈现出人类所看到的颜色。紫外线反射率与羽毛中色素的存在以及影响光反射特性的结构排列有关。羽毛具有很强的紫外线反射特性。具有强紫外线反射的羽毛称为 A 型，无紫外线反射的称为 B 型，具有弱至中等紫外线反射的 A/B 型。假设鸟类是四色酸盐，讨论了鸟类的色觉及其可能的色品图。如果红色、绿色、蓝色和紫外线是原色，则日光光谱中存在三种二次色：黄色、蓝绿色和紫紫外线。另外三种二次色调可能源自混合光谱光：紫色（红色和紫色）、“鸟紫色”（红色和紫外线）和“绿紫色”（绿色和紫外线）。一些具有双带反射曲线的羽毛会产生日光光谱中不存在的色调。
The spectral reflectance of feathers was measured in the range between 310 and 730 nm by means of a diode array spectrometer. In many feathers an ultraviolet (UV) reflection adds to the reflection in the visible range which causes their coloration as seen by man. The UV reflectance is related to the presence of pigments in feathers and to the arrangement of structures which influence the light reflecting properties. Feathers giving strong UV reflecting properties. Feathers giving strong UV reflection are called type A, without UV reflection type B, and giving weak to medium UV reflection type A/B. On the assumption that birds are tetrachromates, color vision in birds and their possible chromaticity diagrams are discussed. If red, green, blue and UV are primary colors, three secondary colors are present in the daylight spectrum: yellow, blue-green, and violet-ultraviolet. Three more secondary hues may originate from mixing spectral lights: purple (red and violet), ''birds purple'' (red and UV), and ''green purple'' (green and UV). Some feathers with double-banded reflectance curves will produce hues which are not present in the daylight spectrum.
