I am using IntelliJ IDEA Ultimate Edition 2018.1.5, and incredibly, I cannot find an option to change the color scheme for the entire IDE. The best I can do is get it to change in the editor panel, so the rest of the environment is unmatched.
What I mean to say is, I can choose between two default color schemes for the whole IDE: light and dark. But these stay the same regardless of what external theme I try to apply. Any new themes only affect the editor. Here is a picture of my attempt to apply Solarized light:
The editor has the new theme, but everything else is still white.
Please, can someone tell me how to change the color scheme? It is really baffling that this is not an easy process like with Eclipse, VS Code, Netbeans, or any other IDE or coding editor I can think of. Especially considering that this is a paid program that costs hundreds of dollars per year. There has to be a way to do this simple thing, right?
