For cases like you describe (the smaller yellow rectangle not being visible just because it is on top of another yellow rectangle), then you will have to use image processing techniques, at least in the general case. If you only have rectangles, then you could go through your document to find them all, determine their extents, check if they overlap, see if they have the same fill colours, etc. You can use the convolution filter to do some edge detection, but I’m not sure if that will give you exactly what you want.
