attr_accessor :colour in your class would allow you do to this:


class Dog
  attr_accessor :colour
end


jimmy = Dog.new
jimmy.colour = 'brown'

puts jimmy.colour # "brown"
jimmy.colour = 'black'

puts jimmy.colour # "black"



As far as i know the name attr_accessor is chosen because it unites both
attr_reader (getter method) and attr_writer (setter method). (There also 
exists attr :foo but I never use attr )
