Matisse Australian Sky Blue is a simple blend of Ultramarine and Titanium White. It is very convenient to have this mixture in a tube as the sky forms such a large portion of many landscape paintings and this colour is a great starting point for making sky colours. It would be a mistake in most instances to just simply paint an entire sky using the blue from this tube. Sky colours vary a great deal from day to day and even from hour to hour. The sky overhead is often a deeper colour than this but the colour changes as you look closer to the horizon and near the horizon the sky is often a lighter and softer eggshell blue. No single colour can depict all these shades and Australian Sky Blue does not pretend to do so, but it does do what an ideal sky blue colour needs to do which is provide the base from which to create the variety of sky colors found on the average day.
