Material-theme-jetbrains: Change color excluded directories

[sanderboom]

Is there a way to change the color of the excluded directories (and library directories like node_modules) in the project panel?

The current theming makes it rather stands out instead of fall away ;)

@ChrisRM I think that will be necessary improve many color in this theme.

Looks like this is actually a setting in Appearance & Behavior > File Colors using the Non-Project Files scope. See below.

Thanks @Zarriff for pointing this out. A different default supplied by the theme would still be an improvement :)
