[YihaoJW]

Is that possible to change the color of lambda, I use vim-lambdify with https://github.com/amix/vimrc.
with the background light.
And this lambda is grey and hard to see. is that possible to change the color something like blue?

Problem Solved by using command

highlight! link Conceal Statement

I use this plugin as well and changing the color of conceal group changes that as well and everything that uses the Conceal feature.
