One thing you can do is make comments italic-bold and slightly darker than default code. I use Solarized Dark, so my comments are dark (but I have max brightness and then Solarized Dark is great), plus italic-bold comments. I also use a different font for italic-bold: Cartograph CF. Unfortunately this does not work in Sublime Text as I am unable to mark comments as italic-bold and define a different font for them. But in Vim and Neovim it works great.
