Visual mode highlight in light mode makes text hard to read

[spellman]

Thanks for porting this theme! In light mode, the visual mode highlighting makes a lot of the text hard to read. I've attached a screenshot for reference:

• Left: nvim 0.8 in vimr with doom-one.vim
• Center: nvim 0.9 in Alacritty with doom-one.nvim
• Right: Doom Emacs with default light theme (The coloring is more basic, maybe because I haven't set up treesitter in Emacs.)

In Emacs, the highlight is a medium gray that leaves the text much easier to read. Could the visual-mode highlight in doom-one.nvim be changed to look like the Emacs version?
