For those who are interested in how to change diffview colors based on theme type, I was able to do this with an autocmd on BufEnter the diffview buffers that changes the highlight groups dynamically with base46's type.

There may be a more natural way to do this, perhaps customizing a theme integration like one in the base46.integration dir is most satisfying, but I was unable to figure out how even after reading related documentations and source codes.

why dynamically tho? most use red for diffremoved, green for added. So just use hl_override!
