Marigold Bud in Shadow

I was working on learning a new photo technique yesterday.  The challenge was to create an image using negative space by focusing on a subject in the foreground and blurring the background.  It was suggested to compose using complimentary colors.  I was using macro settings photographing flowers in my garden and saw this tiny marigold bud lurking in the shadows, below the larger lemon-yellow blooms.  It was a yellow green hue, but what a surprise to see the dark green surrounding foliage translated into blue-purple in the final image.  I was very pleased with this result and posted it on FaceBook, Instagram and Google+ for my friends to enjoy too.
