Initially, I wanted to use the CMYK color chart to visualize age periods, but then I decided to abandon the black (key) color and replace it with green, since any period of human life is beautiful and there should not be black periods in it.

So, my version is: Childhood (6 weeks - 11 years) - Cyan Adolescence (11 years - 20 years) - Magenta Adulthood (20 years - 60 years) - Yellow Old Age ( over 60 years) - Green

Live long! And let only bright colors be in your life.
