Pasta is yellow and CuSO4 is blue, so the resulting colour would be green. If you added a larger quantity of CuSO4 you would probably get a slightly bluer colour.
The answer to all of this is, basically, "food coloring." In the case of pasta, this is often done with vegetable extracts; for example, orange pasta may be colored with carrot juice or squash/pumpkin. Black pasta is often colored with squid ink. Green pasta is generally colored with spinach juice. Purple pasta comes from beet juice.
Tomoto
Usually red pasta has tomatoes in the recipe.

Purple is a cold colour.. and my favourite!
You can add saffron whilst making the pasta dough - this will give a yellowy-orange colour. Otherwise, just add food colouring whilst making the pasta dough. If you're attempting to colour pre-made pasta orange, this is far more difficult to do.
The colour blue is a primary colour and therefore cannot be made by any other colour.
