Function and method calls in Darker theme are grey instead of blue in GoLand v2019.2. Is that intended?
Function and method calls should be blue as always.

They are grey.

I have seen similar discolorations with Material Palenight in WebStorm 2019.2.
Similarly for Arc Dark in PyCharm.

I have experienced this in WebStorm 2019.2 with Material Darker. All instance member functions turned pale orange (although they were blue before).
If you want to bring that back, you can locate the rule in Settings > Editor > Color Scheme > %LANGUAGE_NAME% > Instance member function and check the box "Inherit values from":

This will make the function the default (blue) color. I guess, that can help with other themes and other code elements (such as constructors and local variables).
EDIT: I also have rummaged through Material Darker theme XML and couldn't find any trace of these new colors being used. I believe JetBrains is to blame here, like @Tomotoes pointed out before. They probably implemented the same thing from GoLand in every IntelliJ-based IDE.
This happens every once and every update, the default color schemes are updated and with it, custom color schemes have their colors overridden if they do not define a value. It鈥檚 pretty annoying.
Anyway I鈥檝e fixed that and the next update should have the colors back, but I won鈥檛 release it until at least two weeks
Is there a way to get that update before you release it?
