This issue was discussed in detail, I use the following method succeeded https://github.com/spyder-ide/spyder/issues/2350
For Anaconda3 users on Windows 10 ：
Download and install QDarkStyleSheet, in the console input pip install qdarkstyle
open in Anaconda installation path .... \ Anaconda3 \ Lib \ site- packages \ spyder \ app
to find mainwindow.py in the app folder
because you want to modify this file, please backup! ! After reduction in order to facilitate inappropriate
open this file in from __future__ import print_function which add back then import qdarkstyle (or in a random location import of these statements)
to find this class in this file the following section: class MainWindow (QMainWindow):
Found this function def __init __ (self, options = None):
Add back ((self) QMainWindow .__ init __ ) this function first sentence:
self.setStyleSheet (qdarkstyle.load_stylesheet_pyqt5 ()) and save the file
in Tools-> Preferences-> Syntax coloring-> Scheme in the election like a dark theme (this only for the editor and console, if it does not change anything else this step will find only the title bar of the task bar or white, do not call the complete dark theme)
to save and restart Spyder
Note : If that can not see the Spyder3 icon theme instead of the theme in the Spyder2, Preferences in the General.
OK ~ Happy coding ~~
