Adjust visibility of the light mode toggle

[naschiii]

Is your feature request related to a problem?
I noticed that the toggle for switching from light mode to dark mode is almost invisible in the light mode.

Describe the solution you'd like
Therefore, I would suggest that you change the background color of the toggle from #ececec to #6482ff.

Describe alternatives you've considered
An alternative would be to change the entire background of the website. However, it should be noted that the text would still be legible.

Additional context
The color #6482ff is also used for other elements on the website and in addition, the toggle then looks like a sun with a blue sky.
