I'll use solid white only occasionally for a strong look, usually with a strong color as the back; fluoro orange, blue, black, etc.
If you're going for minnows, silver or silver with a tint is your best bet. Pearls and hilites are your friend here. For baby bass, silver tinted green or yellow is probably ideal.
Frogs, pearl with a yellow tint is my match around here. Add to that a light amount of smoke scrap or some .040 black flake.
Fry tend to be pretty clear, so bellies should be too, clear with a touch of hilite and some .015 holo silver or some of the micro glitter Tom is fond of.
