About colors of `ein:cell-output-area`

[yefeiyu]

1, The emacs's background color is white 2, Defined the ein:cell-input-area's background color is white too. 3, Defined the ein:cell-output-area's background color is black. Now 1 and 2 is OK, but 3 can't consistent. If the cursor at the output-area, the ein:cell-output-area's background color is black; when the cursor move to input-area, the ein:cell-output-area's background color become black (this is the emacs's background color).

How to make ein:cell-output-area's background color fixed?

[yefeiyu]

It changes with cursor's position at input or output area to emacs's background color or definated color. How to make it fixed ?

[yefeiyu]

When I set:

'(ein:cell-input-area ((t (:background "white" :foreground "black"))))
 '(ein:cell-output-area ((t (:background "black" :foreground "white"))))

the input area shows normal, but the output-area discoloration with the position of the cursor.

As my test, it is because this two lines in .emacs: '(ein:polymode t)

But If I comment out these two sentences, Auto-completion will fail in ein.

How should I do?

[yefeiyu]

Today, I tried to modify from

(custom-set-variables
'(ein:polymode t)
)

to

(setq ein:polymode t)

The color of output-area correct, But the result of the ipynb got this error after I input C-c C-c:
