This may seem like a stupid question but how do you cover a cake with one color fondant on top and another on the outside? Do you cover the top and then somehow wrap it around the outside? Here is an example....

Thanks!

For the cake that you showed I would do the white for the top and then wrap the purple around the outside. The upper edge trim would cover the joining of the two pieces.

Yep, cover the top with one color, then wrap around the sides with the other. To wrap it, if you have someone who can help you could roll and cut it to the proper length, then lightly roll it up on the rolling pin. From there, hold the pin upright next to the cake. One person slowly unrolls the fondant while the other smooths it into place.

It might be easier if you cover the cake in purple fondant ( or bc) and then add a second piece on top for the white.
This way you don't have to mess with wrapping the sides with fondant.
Here are a few 2 tone fondant cakes I did this way.
