Very indeed. But the weirdness will only occur along the substrate line, against the wall of your tank. What you can do is lay the black substrate down but make sure it doesn't touch the sides of the tank, then lay the wihte sand.

Why do you want to do that in the first place? Just using the light substrate is adequate.
