Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors.
颜色是光谱(与波长相对应的光能)与眼睛里敏感的光线感受器相作用的结果。

The larger sensor also means that - all other things being equal - full frame cameras will produce the best results in very low light and at higher sensitivities.
