Im not sure what colors you will get but I do have to say, you will have a bunch of fun with these little guys. I have a pair of regulars, maybe getting a pair of whites next year. They are getting a new fully featured enclosed pen this year to. I spoil them just a little.
Here is a website I found you can take a look it has a lot of good info on the whites breed with regular.

Split to white is a term commonly used to decribe those birds that are regularly colored but have the genetics to produce some color mutated offspring, in this case white. These birds normally aquire these genetics by having one white parent. Listed below are breeding results that I have recorded from my own breeding program, for the four available mandarin pairs listed above. Percentages are approximent and may vary some from your own results.
Regular Mandarin Pair- all normal colored offspring
White Mandarin Pair- all white offspring
Split/White Drake w/white hen- 60-70% white offspring all of the remaining regular colored birds will be split/white.
Split/White Drake w/reg colored hen- 20-25% white offspring about 50% of the regular colored offspring will be split/white while the other half will not carry the white gene. It is noteworthy to mention here, that there will be no way to tell the split/white birds from the regular ones except thru careful breeding.
