Vimdoc color issues when conceal is off

[ckipp01]

Hello! Thank you for this incredible colorscheme. I'm absolutely loving it so far. I noticed something today which is maybe a bit niche and I've honestly never really thought about the highlight groups that are at play here, but in my own plugin I am often editing my *.txt help file. When conceallevel is set to 0 things like * or | are pretty impossible to see in various places. I'll give you a couple examples:

* in headings

Notice it's not visible at all unless you are on top of it

Usages of |

Notice here that they are really hard to see by are actually around every command in that list. You also notice in that shot that the "`" is incredible hard to see as well

Let me know if there is anything else I can provide for this. Again, wonderful colorscheme. I'm really really enjoying it so far. Here is a little beauty shot:
