Violet's answers are perfectly correct in a way but I wanted to elaborate on the first point.

This is a complex question and I'm going to split it. How can you palshift the colors of all instances of an object? This is not too difficult. In most cases, all you have to do is change their preset's behavior to something like this on level load:
Code:
void newBehavior(jjOBJ@ obj) {
obj.behave(BEHAVIOR::oldBehavior, false);
jjDrawSpriteFromCurFrame(obj.xPos, obj.yPos, obj.curFrame, obj.direction, SPRITE::PALSHIFT, value);
}
where the parts in red should be replaced by appropriate identifiers / literals.
Now, getting to the "namely snow" part; this doesn't solve your problem because you seem to have gotten it wrong. Snow instances are
not objects. Or, to be unambiguous, they are not jjOBJ instances. They are particles, i.e. jjPARTICLE instances. As such, their options are much more limited. The main problem, as you can imagine, is that you cannot change their behavior. This is a major obstacle but can be overcome by creating snow that is either stored in jjOBJ instances or, preferably, instances of a custom class created for it. In either case you would need to know the default behavior of snow instances, which I believe I'm allowed to provide, and base the new one on that, and that would essentially do the trick, but you would have to prepare to face another problem - this time of much more prosaic nature. You said "144-159". You should be informed that the default snow sprite uses entries 128-136
and entry 201. I suspect that last one could, depending on the exact palette, force a change in your plans.
Anyway, the point is, although it requires an inadequate amount of effort, applying PALSHIFT to snowflakes is essentially possible.
