Bring water to a boil in a large pot. Add the pasta and cook according to package directions, or until it's done to your liking.
While the pasta is cooking, pour 2 Tablespoons of water into a plastic Ziploc bag. Then add 20 drops of orange food colouring.
Seal the bag and swirl the contents together to combine.
Repeat with purple and green food colouring in two other separate bags.
Once the pasta is done to your liking, drain out the water using a strainer.
Return the pasta to the pot and then divide it equally into each bag.
Seal the bags and shake/squish the pasta around to spread the colour over the pasta.
Let the pasta sit in the bags for 5 minutes to absorb the colour.
Empty the bags, one at a time, into the strainer and rinse off any extra colour.
Add the pasta back into the pot then add butter or margarine to keep the pasta from sticking together. Stir until the colours are mixed.
Your Halloween pasta is ready!Add to a plate, serve with parmesan cheese or the sauce of your choice (read some options below!), and enjoy!

Notes
We made 1/2 a package of pasta, but you can make whatever amount you need. If you make more or less pasta, adjust the amount of food colouring as well.
Want to make only one colour of pasta? You can add the food colouring right into the pot of water.
