***Mac users*** - Unfortunately tkinter and the Mac haven't been playing well together when it comes to colors, in particular button colors. For this reason the change_look_and_feel is "disabled" for Macs, however you can force it by assing the parameter to the call `force=True`. You may be able to get away with the change if you change the button settings back to the default setting by calling `set_options`.
## Look and Feel Theme Summary
Here is a quick-reference view of the available Look and Feel themes.

Here is the code that produced it so that you can run it on your system to see the current list of themes and how they appear on your monitor.
```python
import PySimpleGUI as sg
WINDOW_BACKGROUND = 'lightblue'
def sample_layout():
return [[sg.Text('Text element'), sg.InputText('Input data here')],
[sg.Button('Ok'), sg.Button('Cancel')] ]
layout = [[sg.Text('Here is a complete list of themes', font='Default 18', background_color=WINDOW_BACKGROUND)]]
row = []
for count, theme in enumerate(sg.ListOfLookAndFeelValues()):
sg.change_look_and_feel(theme)
row += [sg.Frame(theme, sample_layout())]
if count % 2:
layout += [row]
row = []
sg.Window('Window Title', layout, background_color=WINDOW_BACKGROUND).read()
```
