Hi, Carrie —

There is no difference whether white wine or red wine is used at Mass. It is an option either way.

You said:

• Also, why is there one dice at the bottom of the cross at Easter time?
  

I don't know for sure, but I imagine the symbol of the dice at the foot of the cross represents that Gospel account of the soldiers throwing dice for the ownership of Jesus' garment.

Hi, Carrie —

There is no difference on whether Mass is celebrated with red versus white wine; it's just a matter of taste.

I'm not sure what you mean with respect to the die at the bottom of the Easter candle. There are five grains of incense, representing the five Wounds of Christ. These grains are usually embedded into red wax shapes (nails) that might resemble dice, especially from a distance.

For example, here is a close up:

See Paschal Candle from Wikipedia for more information.
