when I born I black

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 folks...
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 yellow, when you sick you green
when you bruised you purple, and when you die you gray
so who you calling coloured?
