Change the color of unused variables

[madflow]

So I am a Neovim Theme N00b...

I believe only recently, the color of an "unused" variable changed to a degree, that I cannot read the variable names properly anymore. I cannot point the finger on the color value I have to customize, to make it readable for me.

Example:

I want to change the color of the variable "local a", which currently is a dark gray I would assert.

You can always check the hl groups with :Inspect on Neovim >= 0.9

Thanks, working now!
