That would be so sad! I love nature, I love animals, flowers, etc. I love taking pictures of insects going on flowers, etc. I find that fascinating to observe the richness of colours in the the wings of a butterfly. What a gift it is to observe nature change throughout a year like a tree with light green leaves in the Spring. With Summer coming, the leaves become a darker shade of green and then with the Fall, they turn in all those colours going from yellow, to orange, some red or brown. A life without colours would just be bleak!
