Drumroll, please! The odd shape out is ... the big red square with a black outline.

While that might seem like the very last shape you'd say was the odd one out, that's actually the reason it's the answer. It shares its color with three other shapes, its size with three other shapes, and its outline with three other shapes. No shape shares as many qualities with the others as this one does, and that makes it the odd one out. Did you get it?
