I think we all like to clutch cameras at this time of year with the noble intent of gaining snippets of colourful reality. Posies and tulips are everywhere and it won't be long before the first few roses blossom too. Yet, I often walk around my own garden looking at leaves. Mostly because I live in the vain hope that, one day, I will be able to recognise a plant by its leaf, but also because I am totally enamoured with the colour green. At this time in particular, it is fluorescent green, especially on those days when the sky is veiled, the light is grey and nature is unashamedly in your face.
