(set-face-foreground 'ac-candidate-face "black")
;(set-face-underline  'ac-candidate-face "blue")

;(set-face-background 'ac-selection-face "cornflowerblue")
(set-face-foreground 'ac-completion-face "purple")
;(set-face-background 'ac-completion-face "green")

Answer 1

They are not auto-complete faces but "popup faces".

The first face you are looking for is popup-summary-face

The second face (the one with the yellow background) you are looking to change is popup-tip-face

Just do a Mx customize-face RET popup-summary-face,popup-tip-face and you can play with them.
