Syntax highlighting with nabla.nvim

[B1LLP4RK]

I managed to setup with nabla.nvim for math expressions.
using this post

But the syntax highlighting seems a bit off when my cursor is on the line with math expressionf
. It is actually difficult to read the greyed out text.

I would appreciate if anybody gives me a hint to fix it.
If my cursor is on a latex expression,
I hope the color highlights make sense or if thats difficult,
I wish the color is just plain blue for the expression.
