little pink houses

These houses aren't really pink ::: they are white or red or purple.

But with my Polaroid SX-70 and Impossible Project PX 70 Color Shade PUSH! film, they are pink.

I am on a serious quest to figure out how to get more color variation. There are some good conversations about this here and here and it seems that I am not the only one experiencing these pinkish tones.  I thought these were overexposed but after reading more, it looks like I have to push it farther and flood it with light. Any other suggestions are welcome...

As pink as they are, they are still quite nice.
