Yes, this is actually the case, in comparison to other species our color vision is quite good (much better than dogs for example who only see few colors). As you pointed out, we are better at discerning shades of green which makes sense from an evolutionary perspective. That being said, in comparison with most mammals and birds our ability to see in the dark is quite poor. Also, birds such as the eagle have an eyesight far superior than us which allow them to track down prey from distance at high speed.
