[4.0][a11y] Insufficient label contrast ratio at all switches

[zwiastunsw]

Steps to reproduce the issue

1. Go to Backend, for example on the Global Configuration page or on the Modules > Site Modules > Article Category
2. Check the color contrast of the switch labels
   

Expected result

Minimum required contrast ratio >= 4,5

Actual result

The labels of the options set by the switches have too low contrast to the background:
On the Global Configuration page the color combination #868e96/#ebeff5 has a contrast ratio of 2,88. Consider using the following foreground/background combination: #636e79/#ebeff5 / has a ratio of 4.51
On the Modules: Article Category page the color combination #868e96/#fefefe has a contrast ratio of 3.29, which is not sufficient. Consider using the following foreground/background combination: #6d7781/#fefefe / has a ratio of 4.52

Shouldnt this be posted in the private template repo?

[zwiastunsw]

Sorry, but.... where is the private template repository?

[brianteeman]

I have no idea. Obviously I was mistaken in assuming that when they said they had accessibility experts that it included the JAT

@puneeth2001 You do not need to ask for permission. Go for it.

@Quy is it ok:

@puneeth2001 : Don't ask if it's okay. Do PR. Testers will evaluate.
