Okay!
She settles down, and pokes at her notes.
She's been implicitly working on a big ass project on the lights for... a while now? Mostly she's just been letting herself be battered around by what seems shiny at the moment, and there's a certain merit to that approach for something so empathic, but that doesn't mean she shouldn't write out what she's trying to make, more broadly.
She wants a proper suite of things for each of the colors - 'things' here defined to be a power source, a ring, and the at least theoretical capacity to go and make more devices on theme as she desires. Ideally, she should be able to learn to use a large swathe of them, and be able to teach them, share them, the whole shebang. Nothing about what she's doing is completely singularly special, and she's pretty sure from the blue body enhancement intuition that it's not some... physical structural property or anything that you need, just a mind opened up in the right way. It should work in space too just fine, which is a nice little benefit of going for something like this over thaumaturgy.
It's a little unforunate that she had to make as many design concessions as she did for the violet power system - she's pretty sure there's still the conversion system there just fine, and she even managed to get it to work off her own loves to empower itself. She's... going to nurture it a bit more, if only as a little empathic pet project. She doesn't have the power socketed any more, but she's still pretty sure that that's an approach that's natural, for nurturing love, anyways, so it's not like it'll be a waste, in terms of productivity, persay? Maybe integrate ring functionality into it, throw it together as part of a dedicated crafting system... She's pretty sure the "Star Sapphire" has a basically integrated system like that, so it's not out of the question, for all Zatara dinged her a bit for her previous lack of singular vision.
The hope she had earlier is that she could make the whole thing 'work' ultimately off of a singular power system, with the ability to go out and mass produce a bunch of hope-based empathic energy gathering systems, and then either use those to directly empower gadgets, or at least be able to use those to fuel a power conversion system that converts from blue into a desired color to recharge, if it's not simple enough to toss the whole mechanism in like it has been for blue to green, at least if she's trying to do anything more complicated with it.
Her experiments with love seem to suggests that if she wants to scale up violet light equipment, that she'll need to just work with the concessions of a dedicated power generation / power conversion suite for exactly violet. Probably it's feasible enough to make personalized violet empowerment systems on say, individual rings if she empathically connects with someone and bonds their loves and passions to it? Which doesn't feel guaranteed, overall. One benefit is that - even though she's pretty sure that it's not entirely this simple, the violet light system she has right now can just accept arbitrary expressions of the blue light and turn it into usable violet, even she's pretty sure that the result wouldn't be quite as good as if it was part of an organic emotional mix associated with love and/or her feelings. She could still go and do that experiment, though - check to see if gathered hope from places associated with love can make it work better, feel the results out that way...
Making a ring should just be a matter of fundamental mastery, nabbing the appropriate symbology skill to get the basic design. Hell, she should probably go and ask about getting some sort of more canonical auspicious day calendar - the magic of the hellenic gods seems... workable enough, and she'd be suprised if Hera doesn't have a holy day that might be useful, if she's going to think about it as a ritual. Though she's not sure how capturing a holiday specifically works - if she needs to be observant or there needs to be observant people celebrating it or how it counts calendars or what have you. A question for Zatara for later, probably.
She's not sure how important lanterns are, but if she's going to make one... probably she should make a blue one? If she's thinking about making a proper dedicated power system, she kind of likes the idea of making something a little bit more ramshackle for the other colors, all fed into by a proper, dedicated, regulatable system. She's a little doubtful it's an efficient use of her time to try to make a proper Central Power Battery until she scales way up and probably gets at least another slot from the gift, but it's worth thinking over a little bit and not totally discarding as an option. She's also kind of curious if making some sort of dense interrelatey network of all the different colors will do something, so that's another reason to get the whole thing, beyond just completionism.
So that leaves... Red rage, yellow fear, orange desire, and indigo compassion to figure out a power system for, given that she's already figured out a reasonably canonical solution for blue, and a reasonably workable one for green and violet.
In spectra order...
Red seems like it's going to be complicated - the easiest pathway she can picture off the top of her head from hope to rage is foiled hopes, and that seems like a bit of a nasty tightrope to walk. She's also just not... a very angry person, generally, and it's going to be a bit of an adjustment to make it all make sense in her head, even with the help of the gift.
Fear seems... possibly decently straightforward? Hope and fear are easy enough to pair - hope you'll succeed, fear that you won't. The motivations certainly entangle further out, and she's certainly far from free from fear, she's still not... exactly the most comfortable working with it. Still, that might be a bit of a bonus, and fear is probably one of the more beneficial of these to be able to manipulate in a light touch way, maybe?
Desire is - direct and simple, probably? Hope builds up your desires and makes you get closer to them. This is probably one of the more simple ones, unless she's missing something> She might be very well missing something - there's a feeling she's not... grasping everything, here, and she's not totally sure on what the difference between the two is supposed to be, anyways.
Compassion, on the other hand, seems like it's a natural pair for hope in a promotional way, and in a way that mostly doesn't blend together in her head too much? She's pretty sure that she's a decently compassionate soul, too, for all that she finds it a little easier to be driven by more hopeful things, a lot of the time.
Which implies a rough ordering of... compassion, desire, fear, rage? That sounds about right, though honestly she should probably integrate more colors into her walking around powerset if she's going to be working on these regularly.
Oh and yes! She got away with skimping on violet base - that probably explains a decent chunk of why it took more out of her, given that she didn't have quite the same quality of gift supported foundations on the subject, especially given that she wasn't really in love, at the time? The experience gives her a bit more of an appreciation of having taken that for green and blue before doing too much with them, but she definitely doesn't need it, at least for working on the basics, though...
Honestly, violet is probably her next ring color? She's pretty sure she's a passably natural fit for it, and the way that her life is turning feels like it'll be... good for her, to be thinking about love a little more. It's also just a classic magical girl power source for a reason, and while she hasn't explored the utilities around it in detail she's sure there's plenty to find. She's not... too sure how she wants to prioritize power generation vs. ring making vs. all of the gimmicky things? Probably it's just sort of going to naturally fall out of her desire to explore and how her powersets get frozen by the gift running out of flex, but that'll be what it is. Though that being said, she's pretty sure that ring making is more complicated to do truly right than storage, so that implies she should work that out first, more or less? Though exploring into harder territories is always a good thing.
For now...
She should really work on improving her blue kit, make the lantern, make sure the gift is up to snuff, make some more of the protection amulets, that kind of thing. She'll reroute her powers later, probably - maybe she can swing a visit to Hera's temple or something when she's there and see if they have anything on love-related magic? She doubts Themiscrya has much of a health care bureaucracy, either, so making a proper healing device to demonstrate there sounds like a fun idea.
What does the gift think about making a power for making blue lanterns? Oh, and she feels silly for not thinking of this earlier, but what about for making specifically rings (or the same class of generalized light manipulators that rings are a part of, anyways) of a given color?
