I agree with Lexi; being someone who
does use it,
if you're not wanting to get a headache, you're better off not using it.
I myself haven't tried the fireflower datas for colour,
but to be honest, I figure there are two problems anyways:
1. If it is the same as "type", then potentially no model will appear(or nothing at all, no idea)
2. If you did chose another flower, none of its spellballs would do anything(even
flash to my knowledge).
The only way I know of getting something like that to work is to place down a grow wraith
and add an incredibly fast command four to change all cast spellballs to that colour...
and even then, it doesn't work 100%, plus then you couldn't cast other spells
unless you use a non-lethal gate(like using suction tubes, for example).
Plus then you'd have to make sure everything(at least if they'd be modified, preferably all besides the player)
would have to have an id greater than -1, as you couldn't change the spellballs' ID and you'd have to modify -1. ._.
Er - that's if you want
Pop,
Flo, or
Blink to work, and I don't know about
Flash.
