Colored bases are gret to use under a matching eyeshadow to get a more opaque/deeper color but using a duochrome eyeshadow over a colored base can create completely different effects!
Try using a duochrome eyeshadow on top of a colored base to get different effects from the same eyeshadow.
Black bases usually bring out the duochrome but I love to experiment with different colors :)
I swatched some examples of duochrome eyeshadows and pigments over different colored bases
