Does all leaves on earth have individual facets/hues?

Does the leaves on trees, bushes etc. all have individual hues or facets? It seems impossible for any organism to be identical in every way to another, as a lot of factors contribute to diversity. For instance, different amount of shade/sunlight would change the structure of an individual leaf or petals appearance.

Does anyone know for sure? Does all leaves on a single tree have the exact same color?
