I have figured it out.
it is not that I had it wrong. Just that the background was not 
refreshed. by adding "self.show ". It now refreshes itself

here is the program as it stands.

Shoes.app do
	 background 'rgb(0, 0, 220)'
	 line 10,10,300,300
	flow do
		quit = button "quit" do
			exit
	        end
		button "change" do
			color1 = rgb(rand(255),rand(255),rand(255))
			background color1
			self.show
		end	
		button "change2" do
			color2 = ask_color("Give me the Color")
			puts color2.class
			background color2
			self.show
		end
	end
end
