问题
That gray blob right before 0. Please identify the feature, and, if possible, tell how to change the color of this hint.
I'm a fan of JetBrains IDEs, but only occasionally I use Java. Seen this feature some time ago, but totally forgot what it is :(

It is a parameter name hint. These can be disabled for that constructor with an intention (AltEnter) on the parameter itself or in Settings | Editor | General | Appearance. The color of the hint can be changed in Settings | Editor | Colors & Fonts | Language Defaults | Inline parameter hint.
