Both are fine but have to be certified kosher for Passover.
Both black & white pepper originate from the same source. They come from the peppercorns of the plant pepper nigrum. The difference is in the way they are harvested. Black pepper comes from peppercorns that are harvested when green & allowed to dry in the sun until they blacken. White pepper comes from peppercorns that are allowed to ripen fully before picking & then are soaked in water to remove the outer hull.
White pepper is from exactly the same plant as black pepper (Piper Nigrum), sometimes called "peppercorns". White pepper is actually a black peppercorn, but with the shell removed - this means that white pepper is slightly mellower in taste. White pepper has the advantage that, when used in a dish where ground black pepper would be visible, it can be used for a more aesthetically pleasing result. For example, when black pepper is used to season scrambled eggs, it leaves visible black specks. This can be unnerving to a diner who would not usually expect to find black specks in their food; using white pepper negates this situation without compromising on taste.

The edible parts of black pepper are primarily the dried berry, which is the peppercorn itself. This small, round fruit is harvested when it is still green and then fermented and dried to produce the black spice commonly used in cooking. The outer layer of the berry is what gives black pepper its distinct flavor and pungency. Other parts of the plant, such as the leaves or stems, are not typically consumed.

Most Giant Schnauzers are black. Salt and Pepper, which is made up of black and white banded hair, is also an allowed colour. I have also seen Black and Silver, Black and Tan, Red Pepper, and Apricot, but these colours are extremely rare and neither correct nor encouraged.
The botanical name of black pepper is Piper nigrum.
