Conceal color too dark

[ourigen]

Concealed math symbols in LaTeX are too dark to see.

Conceal is linked to fg_gutter so I would need to override fg_gutter which then affects a number of other elements that depend on fg_gutter. Could the default be changed to something brighter?

There's probably another hl group we can change.

Can you post an example .tex file with the settings you use to show as i your example?

[folke]

I made it almost the same as comments now.

@folke Sorry for the late response

The sample .tex in the picture is

This is a test.

Inline math $\sqrt{x^2 + y^2}$

Display math

\[
	a^2 + b^2 = c^2
\]

The conceal settings are VimTeX's defaults and set conceallevel=2.

dark3 is still a little too dark I think. The concealed characters are harder to see when the formula contains many brackets as TeX syntax often have. See:

Another good contender is dark5. It's slightly brighter but fractions are more visible. fg would be even better but I'm not sure if that will affect other use cases for conceal. See dark5:

Formula in example is

$\int{(-\frac{1}{4}(e^{-4t^{2}} + e^{4t^{2}-8}))dt_{1}$

I'd rather not make Conceal any brighter, but like I said there's probably another HL group we can change instead.

What plugin are you using to render the latex doc?

Would be great if you could post a screenshot of running this on those characters

@folke I'm using VimTeX to render syntax conceal.

Here is the result from running :TSHighlightCapturesUnderCursor

Apparently it's not possible to style concealed sections with different hl groups, so I updated the style of Conceal to use dark5 per your suggestion.
