John Marsden said this quote
“ Light is important to us humans. It influences our moods, our perceptions, our energy levels. A face glimpsed among trees, dappled by the shadows and the green-tinged light reflected from the forest, will seem quite different to the same face seen on a beach in hard, dry, sunlight, or in a darkening room at twilight, with the shadows of a venetian blind striped across it like a convict’s uniform. ”
