Re-coloured from this image here:
Orange, by Jgoge through CC Licensing.
My consideration here, as with the previous attempt was to start with an object that was already strongly associated with a colour, and then to break that association. As such an orange seemed like an ideal subject.
A quick search on flickr provided the required image, and I began to tweak the object colour in Photoshop (which didn't actually take very long). When done, I decided to go a little further and add the "Lime" tag at the bottom, as well as the text, just to add to the subject of an orange's change of colour.
