This work has been made in Space & Volume subject. A plaster egg, 15‘5 cm height, must be painted with an abstract pattern and with a specific chromatic criterion. It is not easy to use colour in a non figurative composition, but it is much difficult to do it on a three-dimensional continuum surface. It is also hard to select a shape that works around. It is fantastic to meet students like Emily who understand the proposal and make such nice objects!
