"Hearts of White's effect and hearts of spatial color mixture"

In the upper row, the left heart appears to be darker than the right one, though they are the same luminance (White's effect). In the lower row, where the colors are exhanged between the inset and surround, the left heart appears to be whitish whereas the right one blackish, suggesting the additive color mixture for the former and the subtractive color mixture for the latter.
