Looks like everything got a significant yellow boost the second time around.
LBW is exceptionally saturated compared to LttP...

...but what made it work so well was the smooth detailing of the textures. Picking solid colors out of LBW images (or even averaging them) for ZC palettes will probably get you a look that's even more neon than the original NES palettes. Still, if you were to at least aim in that direction, I believe you'd be doing brightness and saturation increases rather than color shifts.
