Change the color of NVimTreeIndentMarker look terrically hard

[Hierosme]

Hello ,

After 4 hours of hard work i finally open a issue about the color of NVimTreeIndentMarker.

The actual color is almost visible. Execpt for young pepole with a good screen and the light turn to max.

I can change it color by use the cmd:
highlight NvimTreeIndentMarker guifg=#D8DEE9

Where #D8DEE9 is know as nord4 .

Unfortunally for me i have try all i know for change automatically that color. and nothing work.

Is it possible to consider to make visible the NVimTreeIndentMarker ?
or just provide a lua exemple on the README.md about for how rewrite a color.

I have try:
autocommand
autocommand + function
lua highlight

Each time the color turn full white.

Regards
