Better color theming support. More options and improve consistency.

### Description

I would love for Netbeans to support a much larger selection identifiers for selecting colors. Below is a screenshot of Netbeans and VSCode looking at the same method, note that VSCode has a much broader range of identifiers for choosing colors. Also note that the method calls are inconsistent. In the screenshot for example I would expect setUp(), createGUI(), addToPrivateRooms(), etc.. all to be the same color as in vscode.


### Use case/motivation

I find it very difficult to identify the differences between variables, method calls and other keyword identifiers. It is also inconsistent which further exacerbates the issue. If there was more fine grained control on these colors it would vastly improve readability at a glance.

Yes

The issue names no files, tests, or entry points; begin with the attached NetBeans and VSCode screenshot and inspect the editor's color settings. Identify how Java method calls and other identifiers are currently colored, then define the finer-grained options and consistency expected in the example method. Done means the requested identifiers can be distinguished and colored consistently.
