    Except cows can see colour. They only have 2 types of colour receptors in their eyes, compared to humans 3, (missing the red one, from what I gather with 30 sec of googling?) so their colour vision is much more limited compared to ours, but they are not colour blind.

        Sure, but it seems odd to be picky on the use of the word “tree” to refer to the banana tree rather than a herb, but then make the general statement that cows are “colour blind” when they can actually see colour.
