I'm looking for PAIRS of images that are "negatives" of each other:
>one with light colors
>the other with dark colors
>the line-art is otherwise the same, possibly with minor changes to fit the theme
So basically artwork with "light mode" and "dark mode" variants.

I can't just literally use a negative filter, since that looks like ass. And I would like to see some kind of artist's intent in how the two images contrast.

I don't even know what to call it, so it's been difficult to find artwork like that. I'll be thankful for either direct examples or just telling me where to look, or a googleable term for stuff like that.
