For my part, I'd say that there are significant and important reasons to consider the fallibility of our senses, but there is also a difference between rational/practical and philosophical doubt.
If I approach the idea of the color of a leaf philosophically, I might reasonably surmise that the leaf is not truly green, it is only green according to my own language, my own sensory apparatus, and my humanity in general. A mosquito would see the leaf as either hot or cold, not green or orange or yellow.
So, philosophically, the leaf is not truly green. It is only subjectively green. However, practically speaking, the leaf is green if it looks green. And that's all there is to it.
If we were to allow the apprehension of color to be a philosophical question open to doubt, we would be practically paralyzed.
