Sorry Midge:
Doesn't mean that Zed's not colour blind though!Quote:
A few animals can see colour, including man and the other primates, fish, amphibians, and some birds. But most of these animals have a relatively primitive form of colour vision limited to blue and yellow light.
It is only a small group of primates, including humans, that can see the full range of colours ranging from red to green as well as blue-yellow.
