A very nice shot of a red bird in a grey tree with a nice blue sky as the background. However, in my own opinion it does not meet the challenge. With that said I had to give a lower than usual score.
I don't think this is the color on color the challenge called for. The brown on red on blue are a little much. The lighting looks harsh, and the focus doesn't appear to be on any one subject.
Great contrast in colors, but this feels in between; closer in to show more bird, or further back to show more tree with the bird as a bright accent would work for me.
"Take a picture of a colored subject or subjects on the same color background." .. this is a red bird against a blue backdrop.. doesn't meet challaneg for me.
