Colour LBM are
not an option for encyclpaedia entries. The palette is wrong, and so you will get "swimming" effects if any of the pallete entries use the same entries as the game uses for its smoke etc. colour cycling, if brought up during a game screen.
Any LBM to be used for the game therefore
must use the correct B&W palette.
Colour LBM are
only used for the intro screens etc outside the game map screens itself, i.e where the palette is
not in the process of being cycled for smoke, water etc effects. Those LBM are a fixed set (hint - the ones in there that are already in colour
.
