I'm sorry it breaks things for you.
I've tested this on s390x big endian machine, and though that was the 
right place to fix. But I'm not a pixman expert, so I'm probably wrong.

Which application are you using ? Does gnome-character has the right 
colors for you ?

On s390x, most images in firefox are also color-inverted, but I wasn't 
able to fix that.

Feel free to propose a revert.

Best regards,
