TabLine and StatusLineNC highlight groups have very low contrast

I've recently started trying out the iceberg color scheme as my primary vim color scheme. I really like it! One issue I've noticed however is the TabLine and StatusLineNC highlight groups have very low contrast. In the statusline that doesn't matter to me so much, since I don't really need to read the inactive statusline that often. But it's definitely an issue for me to read the text in inactive tabs.

To quantify this, both TabLine and StatusLineNC use the same GUI colors: #3e445e in the foreground and #0f1117 in the background, with StatusLineNC using reverse. This produces a contrast ratio of 1.97:1, which is pretty low.

I could definitely adjust this contrast in my vimrc if I needed, but I figured this was maybe something you'd want to consider adding to the official colorscheme as well.
