Well, this, though for sprites you'll want 05000200 to 050003E0 as those are the sprite palettes' addresses;

05000200:5AA2
05000220:5AA2
05000240:5AA2
05000260:5AA2
05000280:5AA2
050002A0:5AA2
050002C0:5AA2
050002E0:5AA2
05000300:5AA2
05000320:5AA2
05000340:5AA2
05000360:5AA2
05000380:5AA2
050003A0:5AA2
050003C0:5AA2
050003E0:5AA2

these change the sprite's alpha colour (palette index 0 of each 16 colour ramp) to some odd blue (you can replace 5AA2 with something else to get some other colour).
They affect both the scene and the OAM viewer (you'll have to [Refresh] though) and map and tile and everything because they change the actually used palettes.
If it does not work, then the black used by the sprites is not palette index 0 (alpha). In that case, a look at this may help you - it's written for DeSmuME but applies to VBA as well, except there are no sub screen palettes. It's not exactly working towards what you want to do, but covers the information you need.
