I think that the OP is saying that he looked up the colors through M-x
customize-face, not that he *setted* them.

I asked him to make some experiments to determine the source of those
colors, but his last message in our exchange contained only quoted text
from previous messages.

In general, that feature could avoid the scenario where by accident or
ignorance the user sets a background and foreground so similar to each
other that the customize-face interface itself becomes unreadable.

Instead of asking before applying the changes, is could be better to ask
after the changes are visible, using a temporary "safe" color
combination on the minibuffer: "your changes look like this, do you want
to keep them?".
