A surface does not itself have a precise color but rather an ability to absorb certain wavelengths of visible light .A leaf appears green, for example, because it contains a pigment that absorbs red and blue wavelengths, reflecting only green to the observer. As long as the light remains constant, the green appears the same, but as the light source changes (such as when the sun is obscured) so does the color seen by the observer.
The reflection of light from a colored surface has two components. First, some light is reflected unchanged from the first layer of the surface. The remainder enters the substrate and undergoes scattering and multiple reflections inside the material. Eventually, unless the light energy decays within the material, it emerges from the surface as a diffuse reflection. Where the light meets a pigment particle within the surface, some wavelengths will be absorbed while others will be reflected and allowed to continue on their path through the material. Any lig

#一个表面本身并没有一个准确的颜色而是有吸收特定波长可见光的能力。例如一片叶子呈现出绿色是因为它含有吸收红、蓝波长的色素，从而只向观察者反射绿色。只要光线不变，绿色就保持不变，但如果光源改变（比如太阳变暗了）观察者看到的颜色也会改变。
