@sdutoit It's so true, that you notice the colour more. Last year, I did a month of green and this was the outcome http://365project.org/888rachel/365/2014-04-30 Also a month or orange, and one of blue. It's a fun challenge.
@888rachel The collage is a very clever idea to have a few shots at once. The green must have been easy because of grass, nature etc. Purple tricky but then there is Photoshop!
