Yellow and Sparkling are lobs. They hit the very back of the field and sail over your enemies heads but the trade off is they can be returned with anything and they form a zone shot star

White and Sparkling are drop shots. They hit the floor and do a tiny bounce and are a pain in the rear end and force you to the net. They can be returned with anything though and if you aren't prepared for a shot from the net it can backfire on you REAL hard.

Plain yellow are shots that you hosed up on returning and you were off form. They give the other player a zone shot and are a free space on what to hit.

Edit to be more clear.
