In the fight for survival, 

green is losing to a strong army of grey,

But none understood, 

the importance of green as he regulates,

Blue and in turn anger of infra-red and ultraviolet.

Better flow of red, in neural networks, with the toil of fluid through exercise, ensures the well being, of other colors, is what,t needed!

As invisible white and black 

is getting aged in space called time and lays the foundation for the future.
