why *does* cure in ddd sometimes have a pink flower effect instead of the usual green vines

i keep thinking about this and i need. more information. i've only noticed it for riku, when he's linked to certain DE's, but it's not *all* of his links, which means they specifically chose those links to have the pink flower instead of the green vines

the problem is compiling which links have the pink flower (or ascertaining if its random or different based on the level of cure/cura/curaga) bc holy crow that is a lot of work i dont know if i have time for

the easy answer would be for visibility, but tbh that makes no sense to me and given this is kh i have a shovel and i am ready to dig

me, looking at k and her pink flower symbolism in relation to this thread: hey what's up with that
