This is a 42 MPx photo of a fallen yellow leaf on the fern. Sometimes the composition is formed long and complicated, but this is the opposite, the mossy subsoil surrounded by orange leaves directly wanted to add something contrasting, so put inserting a yellow leaf in the middle was a matter of time.
Autumn weather is an amazing variety of color combinations, this is just a shard of possibilities.
