Marble Colour Sorting Machine

I would like some advice for my first project a colour based marbles sorting machine.
Marble colour sorting machine. It is a magical marble sorting machine using a color sensor fom adafruit type tcs34725 and a leonardo arduino from littlebits. The machine sorts four different colors and it also counts the number of marbles per color. It should be composed by a funnel which receives a lot of black or white marbles and channels them towards a small sorting room. Here the colour of the marble is determined and based on it the marble falls towards the white or the black exit of the machine.
We would like to show you a description here but the site won t allow us. You can use this colour. All electronic parts are made with littlebits.
