You are talking to a blind man who asks you to describe the colour "orange". Write down what you would tell this man without once using the word "orange" in your explanation. [I'm doing this for all 7 colours of the rainbow as a writing slump cheat. Read my blue and red post.]
The growing light of dawn, and fading light of dusk. The colour of fall. Indeed, it is the colour for the beauty of transitions. As we move from day to night, summer to winter, we celebrate it with a joy that is both warm and cheerful, but not overwhelmingly so. It signals a fleeting beauty, made all the more precious exactly because it does not last. This colour does not take sides, because it embraces both. It is both. So people like it, because it endears to all. If colours can be sociable, then it is the most sociable colour indeed. It is the life of the party, but not the centre of attention! It tastes of wholesomeness - full, complete, yet with a refreshing squirt of tang. This vibrance and enthusiasm comes through clearly once you got a taste of it. Sweet and sour, lively yet steady. You had never seen a more self-assured colour, for sure.
