In a Jazz 2 remake, we could use 7 types of mask:

1) Black: The solid block, that you stand on and stop at.
2) Jazz Transparent: The empty block, you walk through and fall down according to gravity.
3) Intense Purple: Triple gravity, making you jump lower and fall faster.
4) Lilac: Halved gravity, making you jump higher and fall slower.
5) White: No gravity. You can thrust yourself in every direction you want.
6) Brown: Ooze or swamp. You get stuck in it and move slowly, like in SuperMarioLand2's Tree Zone level 2, where you swim in the sap.
7) Blue: Water that you can swim into, like the Water Level event, but limited to the mask.
