This is a fun game, my daughter and I both like it, but who ever decided to use green as a primary color is off their nut and should be looking for work in a colorless world. The game is mixing red and green paints to get yellow (If your mixing light that will work) and blue and green paints to get cyan (there we go again). Parents will need to correct their kids or they will paint everything black and brown because that is what you get when you mix red with green and blue with green in the real world. Why not just make the option yellow paint instead of green? Then we could have smart kids, because most kids will not be mixing lights any time soon. Remember red with yellow = orange. Blue with yellow = green. Blue with red = purple. And the creators of the game said that it was not recommended for people with color blindness, how ironic (said the pot to the kettle)!!!!!
