Color??

This is written by an African:

Dear white fella
Couple things you should know

When I born, I black
When I grow up, I black
When I go in sun, I black
When I cold, I black
When I scared, I black
When I sick, I black
And when I die, I still black.

You white fella
When you born, you pink
When you grow up, you white
When you go in sun, you red
When you cold, you blue
When you scared, you green
When you sick, you yellow
And when you die, you grey.
And you have the cheek to call me coloured?
