I came to scan for the same thing, basically. Is there a vi(m) hex editor?
Hexmode https://github.com/fidian/hexmode or vim-deadc0de https://www.vim.org/scripts/script.php?script_id=6033
With decent color support? No.
I was kinda expecting vim with whatever common plugins I installed to do this already, but no. It does nice highlighting for all sorts of text formats, even non-code things like CSV, but not hex.
