You should:

1. Go to Settings->Plugins and remove Material UI plugin
2. Switch to Default theme in Settings->Editor->Color Scheme

If it does not help (it happened to me) and you still have some colors/fonts from removed Material UI - looks like Material UI theme override some default colors. You should then close Intellij, go to Intellij config folder (on Windows it is C:/Users//.IntellijIdeaXXXX.X/config) and remove this config folder and restart Intellij. It should show you a dialog window to import settings from previous version or use defaults (like when you install Intellij and make the first start). After that everything will be switched to default colors/fonts.
