I'm not sure why are you not sure.

I'm quite sure you know that Emacs displays character glyphs by
drawing the background and foreground separately, and it sets the
colors of each one according to the attributes of the current face.
How, then, will the full-color image be displayed, if we override the
colors it might specify?

Yes, I know.
