Green is an easy color, at least at this time of the year. It sprouts everywhere and nothing is simpler than to hide in a bush and take your images from within, keeping the de-focused leaves as colorful foreground.
Having the choice between green and pink, I chose pink for … the form of a hat? Fact is, I can’t justify this image with rules. I can’t and won’t justify it at all, but I know that it has a certain quality, and I won’t even deny that my grandmother wore hats like this and that there may be a connection.
Edit: as suggested by feedback on the Radiant Vista forums, I have made a variant of this image that eliminates the orange wall in the upper left. Much more harmony, for sure.
