Their cone cells are trained to detect yellow and blue-to-ultraviolet light. Each cone type has a pigment that is sensitive to different wavelengths of light. The spectrum of colors that an animal perceives is determined by a combination of color-sensitive pigments in their eyes and brain processing. Dogs can't discern as many colors as we can since they have fewer cone kinds. Gecko vision In low light, humans cannot perceive colors very well, if at all. This is due to the fact that our cone cells work best in rather strong light. Other cells in our eyes, known as rod cells, assist us in seeing in low light. However, because rod cells only contain a single light-sensitive pigment, humans perceive in greyscale at night. Geckos, on the other hand, have exceptional night vision, which is helpful for a ...
