The picture book where every page was a window

I'm drawing a children's book and every page is a window in the same house, looking in on the same family at different ages — a kid blowing out birthday candles, that same kid older, packing boxes, an empty room with light on the floor. The color separation keeps failing; the sunset red bleeds backward into the morning scenes, and I'm the only one who notices. I wake up before I can fix it, and I'm still annoyed about the red.
