I am trying to construct an infinate list of pairs of random colors.
I am hung up on getting a random color. I have:
data Color = Blue | Red | Green deriving (Eq, Ord, Show)
am I supposed to instantiate a Random class instance from color?
I am not sure exactly how the random number generator
G'day all.
