How much opacity should be used? (+a couple somewhat related theming things)

[this-username-system-sucks-ass]

I've tried a couple different themes, including the alpha theme mentioned in the README (I tried the alpha 50 ones, which is roughly 20%) and a customized breeze theme which has an alpha of 64 (25%) appended to every entry that said background. I like the way it looks with the breeze one, but the low opacity makes text on certain apps, particularly electron and gtk apps which refuse to follow the system colors, varying degrees of illegible. none of them are to the point that it isn't usable (for some specific examples, zen browser w/ this done to it and vencord with the "Discord Mica" theme) but I would like to improve legibility wherever possible. I want to keep the opacity as low as practical because the higher it gets the more sad and gray certain apps like discover and neochat look. My blur is at 50% with no noise. Here's a couple screenshots to demonstrate what I mean:

^zen browser on the kde bugzilla. some of the darker text in the toolbar and under the search bar is a little hard to read. ^vencord on the zen browser discord server. the servers without unread messages are greyed out and have poor contrast. ^the same zen window from earlier, along with discover and dolphin. neither has any weird greyed out text anywhere, however everything below the titlebar in discover is sad and grey.

the contrast issues with dark text in the first two are pretty typical from what I've seen. I'd like to have something that automatically adjusts the text colors to account for the contrast but plasma just doesn't support that afaik. maybe this will be fixed with the new theming system, maybe not. either way, the best I can think of right now is to fine-tune my opacity.

as for the third, I'll pick dolphin as the golden example of an app properly conforming to what I'm going for. It has no weird greyed out text anywhere, it uses system context menus so they are properly blurred, and since it has a real header bar (that being it's toolbar) it doesn't make the titlebar look like it was tacked onto the rest of the window as an afterthought. I probably could have found better examples of a worst offender than discover but the goal was more to show the sad greyness I was talking about. that gets worse and worse the more opaque it is until at some point it's just breeze dark. I've messed with all the color scheme stuff I can but literally no option changes it, including a 0 alpha value on the view.

in case anyone wants to mess with it, here is the modified breeze color scheme:

no replies yet but I want to add that I've since figured out that no setting can change what I was talking about with Discover so i'll just have to wait until the new themeing system comes out for that. also, I've since settled on 128 (50%) with blur just high enough to render text illegible.
